CHANGES IN VERSION 1.7.11 ------------------------- USER-VISIBLE CHANGES - Adds warning in make_network() and error in plot_network if empty graph encountered Issue 275, check/warning for empty igraph objects https://github.com/joey711/phyloseq/issues/275 - rarefy_even_depth() messages changed from cat() to messages(), and optional verbose argument added https://github.com/joey711/phyloseq/issues/263 CHANGES IN VERSION 1.7.10 ------------------------- USER-VISIBLE CHANGES - Fixes build-error originating from change in ade4 NAMESPACE in version 1.6.2 - Change minimum ade4 version to 1.6.2 - Uncommented examples now included in documentation for DPCoA function CHANGES IN VERSION 1.7.9 ------------------------- USER-VISIBLE CHANGES - Fixed typo-derived bug in new vignette. - These changes allow user to build from source without error. CHANGES IN VERSION 1.7.8 ------------------------- USER-VISIBLE CHANGES - Package dependencies reduced/clarified: https://github.com/joey711/phyloseq/issues/259 Should reduce chances for collisions with other packages, and related issues. Removed any dependencies on the picante package. - Replaced picante::node.age() with a faster implementation, node_ages() Appears to be 3 times faster. Speeds up UniFrac() and tip_glom() calculations. CHANGES IN VERSION 1.7.7 ------------------------- USER-VISIBLE CHANGES - Tree fixes: https://github.com/joey711/phyloseq/issues/235 https://github.com/joey711/phyloseq/issues/255 - If a tree has NA branch-length values, they are automatically set to 0. This occurs within both phyloseq(), and read_tree(). - UniFrac calculations require a rooted tree. While a rooted tree is not required to be part of a phyloseq object, it is a helpful default behavior to select a random root when UniFrac is called and the tree is unrooted, flashing a notice to the user. - Precise import from ape-package, rather than full-import. Smaller chance for collisions. Precisely-defined dependencies listed in NAMESPACE - As a result of the previous, phyloseq defines a placeholder "phylo" class, extended from "list". This seems to match the class from a full import of ape, and is necessary since ape does not export the "phylo" class. CHANGES IN VERSION 1.7.6 ------------------------- USER-VISIBLE CHANGES - Merged branches 1.7.4 and 1.7.5 CHANGES IN VERSION 1.7.5 ------------------------- NEW FEATURES - User-specified axis ordering to plot_heatmap() - User-specified axis edges to plot_heatmap() - This addresses: [Issue 237](https://github.com/joey711/phyloseq/issues/237) [Issue 230](https://github.com/joey711/phyloseq/issues/230) USER-VISIBLE CHANGES - New arguments to plot_heatmap(): `taxa.order`, `sample.order`, `first.sample`, `first.taxa` CHANGES IN VERSION 1.7.4 ------------------------- NEW FEATURES - import_mothur now handles more formats - Added documentation to discourage .group/.list formats CHANGES IN VERSION 1.7.3 ------------------------- NEW FEATURES - Added phyloseq_to_deseq2() wrapper function and examples for computing multiple OTU tests using Negative Binomial model and GLM (DESeq2). USER-VISIBLE CHANGES - Also added new .Rmd vignette for using DESeq, with colorectal carcinoma data CHANGES IN VERSION 1.7.2 ------------------------- USER-VISIBLE CHANGES - Reformat NEWS (this) file. CHANGES IN VERSION 1.7.1 ------------------------- USER-VISIBLE CHANGES - Rmd/HTML-based vignettes. No more Rnw/Sweave/PDF - Updated installer CHANGES IN VERSION 1.5.23 ------------------------- USER-VISIBLE CHANGES - Update dependency from igraph0 to igraph - Requested by CRAN - igraph0 is being deprecated, removed from CRAN - igraph is actively updated/maintained. igraph0 isn't / soon won't be. - The load bug that I could find from re-running the tutorial in the new dependency had to do with accessing the vertex names. The appropriate function is: `get.vertex.attribute` which was not used previous, but is now imported and used in this version of phyloseq. - This also closes [Issue 247](https://github.com/joey711/phyloseq/issues/247) CHANGES IN VERSION 1.5.22 ------------------------- USER-VISIBLE CHANGES - Fix minor bug in `import_mothur` - Bug occurs only when sample names are pure integers. One line fix. - This addresses [Issue 242](https://github.com/joey711/phyloseq/issues/242) CHANGES IN VERSION 1.5.21 ------------------------- USER-VISIBLE CHANGES - `plot_richness` / `estimate_richness` updates - Additional alpha-diversity measures added to both functions. - New argument, `measures`, added to both functions, allows user to specify which measures to calculate/display. - Also added unit tests for both functions, absent in prior versions CHANGES IN VERSION 1.5.20 ------------------------- USER-VISIBLE CHANGES - Bugfixes, `read_tree_greengenes`, and a `replace` optional parameter to rarefy_even_depth() - read_tree_greengenes() is a new function created specifically to address the problem created when the greengenes consortium chose to publish their official release trees with semicolon-delimited node labels, even though semicolons are also a special newick character. The semicolons only appear when a node has more than one taxonomic rank assigned to it, which is rare in the smaller (lower OTU similarity threshold) trees, but a big problem in all the most commonly used trees, e.g. 97% tree. The hard part was identifying the precise cause of the problem. Now that it is precisely known, the offending delimiters are temporarily replaced so that the standard parser `read.tree` can create the phylo object, then they are reinstated. Unit tests have been added to check that this works properly on a GreenGenes release tree that otherwise breaks `read.tree`. This also solves 224 https://github.com/joey711/phyloseq/issues/224 - Fixed a bug in which the highest taxonomic rank fails in `tax_glom` This was a bug resulting from the automatic coercion of single-column matrix subsetting to a vector. Simply changing the relevant line of code in `tax_glom` such that [, , drop=FALSE], solve this issue, Issue 223 https://github.com/joey711/phyloseq/issues/223 Unit tests have been added that should catch this in the future. - rarefy_even_depth() new option to sample without replacement. Two implications to consider are that (1) sampling with replacement is faster and more memory efficient as currently implemented; (2) sampling with replacement means that there is a chance that the number of reads for a given OTU in a given sample could be larger than the original count value. This is in contrast to sampling without replacement where the original count value is the maximum possible. Prior to this phyloseq version, this `replace` parameter did not exist and sampling with replacement was the only random subsampling implemented in the `rarefy_even_depth` function. This prior behavior was selected for computational efficiency, but differs from the behavior of analogous functions in related packages (e.g. rarefying in QIIME). CHANGES IN VERSION 1.5.19 ------------------------- USER-VISIBLE CHANGES - add gap statistic support for ordination results - gapstat_ord() - wrapper function for cluster::clusGap for ordination methods - plot_clusgap() - wrapper function for plotting gap statistic results from clusGap() - Full examples on the soilrep dataset for gap statistic. - Fix bug in eigenvalue proportions for axes other than the first two in ordination plots. CHANGES IN VERSION 1.5.17 ------------------------- USER-VISIBLE CHANGES - replace URL with new phyloseq article http://dx.plos.org/10.1371/journal.pone.0061217 CHANGES IN VERSION 1.5.16 ------------------------- USER-VISIBLE CHANGES - rarefy_even_depth improvements User-side convenience upgrades to rarefy_even_depth() behavior. - More user feedback about process. - New argument for setting RNG seed, with a default value (reproducible by default). - Reports the RNG seed being used for random subsampling, encouraging users to record this for reproducibility. - Trims empty samples/OTUs automatically, and reports this to standard out. CHANGES IN VERSION 1.5.13-15 - build improvements, changed dependencies ------------------------- USER-VISIBLE CHANGES - Shifted RJSONIO dependency to the new "biom" package in CRAN CHANGES IN VERSION 1.5.11-12 - ------------------------- USER-VISIBLE CHANGES - major feature: interface to microbio.me/qiime data repo - Now possible to directly download, unpack, import multi-component data into standard phyloseq form in R using a single command using the new microbio_me_qiime() command. Supports the following input styles: - full URL to the precise study on the server, - a local path to the same compressed raw data file on your system if you already downloaded - Just the study number on the microbio.me/qiime repo. For example: microbio_me_qiime(524) will download and import the "smokers" dataset. - See the following tutorial for more details: http://joey711.github.io/phyloseq/download-microbio.me.html CHANGES IN VERSION 1.5.9 - minor bugfix ------------------------- USER-VISIBLE CHANGES - Bugfix for psmelt()/plotting when entire columns in tax_table are empty CHANGES IN VERSION 1.5.8 - update reshape dependency to reshape2 ------------------------- USER-VISIBLE CHANGES - This satisfies [issue 134](https://github.com/joey711/phyloseq/issues/134) CHANGES IN VERSION 1.5.6-.7 - plot_ordination() ------------------------- USER-VISIBLE CHANGES - plot_ordination() now includes percent variability on axis labels, if possible CHANGES IN VERSION 1.5.5 ------------------------- USER-VISIBLE CHANGES - Update citation info for latest per-reviewed phyloseq article - http://dx.plos.org/10.1371/journal.pone.0061217 CHANGES IN VERSION 1.5.4 - Add taxonomic classification data to mt() output, if available ------------------------- USER-VISIBLE CHANGES - This completes a feature request in [Issue 179](https://github.com/joey711/phyloseq/issues/179) CHANGES IN VERSION 1.5.3 ------------------------- USER-VISIBLE CHANGES - bug fix in plot_heatmap labels derived from ggplot2 change - This solves a bug described in [Issue 192](https://github.com/joey711/phyloseq/issues/192) CHANGES IN VERSION 1.5.2 ------------------------- USER-VISIBLE CHANGES - bug fix pass extra args to `transform_sample_counts` CHANGES IN VERSION 1.5.0 ------------------------- USER-VISIBLE CHANGES - Level up to R version 3.0.0 CHANGES IN VERSION 1.3.23 ------------------------- USER-VISIBLE CHANGES - bug fix for transform_sample_counts - Only appears to affect OTU tables in the "taxa are columns" orientation. It is the result of a surprising behavior of the apply() function, which in this circumstance transposes the table. - This solves a bug described in [Issue 186](https://github.com/joey711/phyloseq/issues/186) CHANGES IN VERSION 1.3.22 ------------------------- USER-VISIBLE CHANGES - additional tests for prun_*() and phyloseq() functions - Before releasing v1.3.21 on GitHub:master some gaps in re-order checking were noticed. These are now caught by new unit tests and phyloseq/prune/etc have been further revised to ensure that properly-ordered OTUs are not disordered during a pruning step. CHANGES IN VERSION 1.3.21 ------------------------- USER-VISIBLE CHANGES - accessor efficiency - For instance, ntaxa() and taxa_names() are very slow on large dataset Some of the highly inefficient approaches are now replaced. The strategy is described further in [Issue 183](https://github.com/joey711/phyloseq/issues/183) CHANGES IN VERSION 1.3.20 ------------------------- USER-VISIBLE CHANGES - reference sequence class update. - formally define the new version of phyloseq-class with refseq slot included - new/augmented accessors: taxa_names, ntaxa, refseq - phyloseq() constructor now supports XStringSet components - reconcile_species internal function removed/replaced - reconcile_species removed from constructor and package. internal, so no need to deprecate. - check the component slot list provided by the "splat" infrastructure - prune_taxa - Rebuild current example data. - print/show methods. - subset_taxa - add refseq (XStringSet) object argument to import functions. import_qiime, import_biom - merge_phyloseq: works with refseq data - Add merge_taxa method for XStringSet objects - Include reference sequences in example datasets - prune_* / reconcile_* / intersect_* . add intersect_samples() function, model after new version of intersect_species() rename intersect_species to intersect_taxa() rm/replace reconcile_* functions with prune_*(intersect_*(), ps). These changes make simpler / DRYer code. Easier to extend. - DRY (and hopefully speed) improvements to merge_taxa(). Additional speed improvements may be possible for tip_glom, tax_glom in later revisions CHANGES IN VERSION 1.3.14 ------------------------- USER-VISIBLE CHANGES - Shortened/replaced examples in the longest-running doc examples. This substantially reduces the time it takes to run package checks. - Focused on worst offenders - Created a new online tutorial for `subset_ord_plot`. Linked to it from `plot_ordination` - `plot_taxa_bar` moved to deprecated function file where it belongs, and examples completely removed from doc. CHANGES IN VERSION 1.3.13 ------------------------- USER-VISIBLE CHANGES - Fixed unofficial warning from missing (unregistered) classes of ordination objects. Stems from the internal get_eigenvalue being defined as S4 generic instead of S3. Solves the following logged issue: https://github.com/joey711/phyloseq/issues/166 - Name of get_eigenvalue generic replaced with extract_eigenvalue, in addition to re-defining as S3 generic. - Fixed ggplot2 warning from over-specified "bins" in the plot_scree bar plot. Changed to stat="identity", solves problem - Fixed warning when eigenvalues get (slightly) negative. They are now set to 0.0 for the purposes of plotting in plot_scree. CHANGES IN VERSION 1.3.12 ------------------------- USER-VISIBLE CHANGES - Fixed a parsing issue for some QIIME-produced .biom files that had leading space characters. Issue further described at https://github.com/joey711/phyloseq/issues/171 Fixed such that any number of leading/lagging space characters are removed from taxonomic classification entries - Fixed build issue on some windows machines derived from problem with figure files having colons in the filename. CHANGES IN VERSION 1.3.11 ------------------------- USER-VISIBLE CHANGES - Added tree option for import_biom() importer so that users can avoid using merge_phyloseq() if their files are otherwise standard vanilla - Address Issue 169 and 167 https://github.com/joey711/phyloseq/issues/169 https://github.com/joey711/phyloseq/issues/167 CHANGES IN VERSION 1.3.10 ------------------------- USER-VISIBLE CHANGES - Added support for Shannon/Simpson alpha-diversity indices in plot_richness https://github.com/joey711/phyloseq/issues/164 - All sample_data now embedded in plot_richness output graphic, in case want to use other covariates in additional layers not originally specified. For instance, if you wanted to include geom_text(label=addLayer1). See plot_richness online tutorial. CHANGES IN VERSION 1.3.9 ------------------------- USER-VISIBLE CHANGES - Added ability to add node labels, bootstrap values to tree graphics generated by plot_tree. - The labeling itself is opened-up as a user-provided function to facilitate custom node-labeling needs (including symbols and other ggplot2 geoms) - Commonly-needed functions are provided as newly-documented exported functions in the package: nodeplotdefault - adds whatever is in the node label to the graphic nodeplotboot - Adds the labels as bootstrap values, coercing/rounding as needed nodeplotblank - Ensures that node labels are not added. - These new functions can be used to give valid arguments to the new `nodelabf` argument in plot_tree(). - Some other re-organization to plot_tree to show more code in the main plot_tree function. CHANGES IN VERSION 1.3.8 ------------------------- USER-VISIBLE CHANGES - Fix bug in plot_tree graphic if sample names start with a number - This fixes https://github.com/joey711/phyloseq/issues/149 - Also added fill argument to default aesthetic map definition, useful if fillable shapes defined in subsequent layers CHANGES IN VERSION 1.3.7 ------------------------- USER-VISIBLE CHANGES - Revisions to plot_tree to improve formatting, organization - "ladderize" contributed by Gregory Jordan - Color scale option removed from original pull request - already supported as core ggplot2 functionality through layering - Added links and roxygen2-header revisions for proper doc formatting - Fixed bug in which alternative size-variables still labeled as "abundance" in legend. CHANGES IN VERSION 1.3.6 ------------------------- USER-VISIBLE CHANGES - Updated basics vignette CHANGES IN VERSION 1.3.5 ------------------------- USER-VISIBLE CHANGES - Updated README.md to point to phyloseq home page (instead of redundant display of content). - Also added README.html CHANGES IN VERSION 1.3.4 ------------------------- USER-VISIBLE CHANGES - Updated tests, examples for merge_samples() - Updated some dependency min versions - First 2013 commit CHANGES IN VERSION 1.3.3 ------------------------- USER-VISIBLE CHANGES - updates to import_qiime() - modular building of taxonomy table in import_qiime() and import_biom() CHANGES IN VERSION 1.3.2 ------------------------- USER-VISIBLE CHANGES - import_biom() fixes. - More robust data handling for taxonomy table - Flexibility: Can take custom parsing function for taxonomy vectors - tests added for new parsing functions parse_taxonomy_default parse_taxonomy_greengenes CHANGES IN VERSION 1.3.1 ------------------------- USER-VISIBLE CHANGES - New function: plot_bar() that is simpler more reliable than plot_taxa_bar. - plot_taxa_bar now deprecated. - labeled deprecated in title doc - replaced examples in vignette with plot_bar examples CHANGES IN VERSION 1.3.0 ------------------------- USER-VISIBLE CHANGES - Level up github devel version number to reflect devel order/status relative to latest BioC release CHANGES IN VERSION 1.1.58 ------------------------- USER-VISIBLE CHANGES - Fixed a bug in import_qiime in which import fails if there are any empty taxonomy string fields in a file that otherwise has some taxonomic assignments. Now the taxonomy entries for that OTU (row in the taxonomy table) are left all NA_character_ by default. CHANGES IN VERSION 1.1.57 ------------------------- USER-VISIBLE CHANGES - Added automatic removal of single and double quotes from phylogenetic tree tip names provided to the phyloseq-constructor. This should help avoid problems importing data that includes a tree, for the cases where the taxa/OTU names don't match because of these extra quotation marks. Added directly into the phyloseq() constructor, so that it doesn't matter how/where the tree was imported/add. - Removal of quotes is only initiated when OTU/taxa names fail to match AT ALL (intersection is length zero) between component taxa names. - This feature needs to be added to unit tests as well. CHANGES IN VERSION 1.1.55 ------------------------- USER-VISIBLE CHANGES - Added "title" argument to plot_scree() and plot_ordination(…, type="scree"), for consistency. CHANGES IN VERSION 1.1.54 ------------------------- USER-VISIBLE CHANGES - Changed "species" label in different plot_ordination() graphics to "taxa" - Fixed an issue with a default parameter in a related internal function (changed "samples" to "sites" for vegan compatibility). CHANGES IN VERSION 1.1.53 ------------------------- USER-VISIBLE CHANGES - Fixed additional title issues in plot_network and plot_richness CHANGES IN VERSION 1.1.52 ------------------------- USER-VISIBLE CHANGES - Added plot_scree() function for making eigenvalue "scree" plots in ggplot2 - Added corresponding type="scree" option to plot_ordination, for convenience. CHANGES IN VERSION 1.1.51 ------------------------- USER-VISIBLE CHANGES - Returned to "Imports:" dependency for ggplot2 following a ggplot2 bug fix CHANGES IN VERSION 1.1.50 ------------------------- USER-VISIBLE CHANGES - Fixed several compatibility issues to support latest version of ggplot2 (0.9.2). - Also changes plot_richness_estimates() to plot_richness(). CHANGES IN VERSION 1.1.45 ------------------------- USER-VISIBLE CHANGES - Backward compatibility for import_qiime_sampleData, now superseded by import_qiime_sample_data - Added a functioning example based on the GlobalPatterns example sample-map file included in the package extdata. CHANGES IN VERSION 1.1.44 ------------------------- USER-VISIBLE CHANGES - Fixed minor bug in tax_glom function. Thanks to Katie Shelef for the bug report. Bug only affected tax_glom behavior when the right-most rank was specified as the position for merging. CHANGES IN VERSION 1.1.43 ------------------------- USER-VISIBLE CHANGES - fixed distance() issue from species/taxa replacement for type argument. CHANGES IN VERSION 1.1.42 ------------------------- USER-VISIBLE CHANGES - fixed make_network/plot_network issue from species/taxa replacement for type argument. CHANGES IN VERSION 1.1.41 ------------------------- USER-VISIBLE CHANGES - Fixed documentation for `prune_taxa` and `prune_samples` - Updated `prune_samples` method to allow for logical vectors. - Fixed `prune_taxa` so that it properly fails with a message if the taxa argument is a logical of wrong length. There was some potential (and no warning) for unpredictable vector-recycling with short vectors in the old implementation. CHANGES IN VERSION 1.1.40 ------------------------- USER-VISIBLE CHANGES - Huge Update and Renaming Event. - Made all functions use an *underscore* for English word delimiter, if they were using an abbreviation. - Replaced "species" in all function names with "taxa". - These changes are all backward compatible, for now, so your old code should work. Let me know if it doesn't and I will quickly make the adjustment. This will remain true through the next official release, but functional references to "species" will not be supported afterward, except in the occasions where you actually mean taxonomic species, like `tax_glom(x, "species")`. CHANGES IN VERSION 1.1.33 ------------------------- USER-VISIBLE CHANGES - Revise taxglom() such that it handles phyloseq and taxonomyTable classes, throws warning otherwise. It should not take a manually-produced character vector, as this is roughly equivalent to functionality supported in other method, especially prune_species()/merge_species(). - Also added unit-tests and executable examples for taxglom(). Got rid of taxglom.internal, incorporated directly into taxglom(). taxglom() is no longer an S4-method, and doesn't need to be now that the character-vector argument option is omitted, with S4-class handling delegated to merge_species(). Updated "taxTab<-" to be S4 assignment, clearer handling of taxonomy Table assignments, especially useful for taxglom. CHANGES IN VERSION 1.1.29 ------------------------- USER-VISIBLE CHANGES - Add unit tests and example files for import_biom (as well as import("biom",...) ). CHANGES IN VERSION 1.1.28 ------------------------- USER-VISIBLE CHANGES - Added rarefy_even_depth() function for random subsampling of microbiome samples to the same number of reads.
