- the estimation was not correct at last distances.
allowed setting the precision of simulated coordinates in gEnvelope().
sorted point types in decreasing order of abundances in autoplot.wmppp().
avoided accessing ppp objects’ marks directly.
cleaned up the code

Bug fixes

Kdhat() density was normalized incorrectly with Approximate=TRUE and small r values.

dbmss 2.6-3

Improvements

More robust check of arguments.
Rcpp >= 0.12.14 required. init.c no longer necessary.
Introduction vignette.
On Travis and codecov.io now.
NEWS in Markdown.
wmppp() accepts characters in PointType. A PointName column is searched to set the row names of the marks.

Bug fixes

wmppp() failed if some point laid outside the window.

dbmss 2.5-1

New features

On GitHub now.
Individual values of m and M available from Mhat and mhat with argument Individual.
Point names can be specified as row names of the dataframe passed to wmppp(). They are preserved in the fv object returned by individual Mhat and mhat to identify points more easily.

Improvements

Far less memory is used to compute M and approximated m functions. The ratio of necessary memory equals that of the number of reference points to the total number of points.
[.wmppp function added to spatstat generics

dbmss 2.4-1

Improvements

Declaration of the required versions of R and spatstat in DESCRIPTION to avoid error in CRAN test on oldrel Windows platform.

Enforcement of the use of C++11 to avoid warnings due to RcppParallel.

dbmss 2.2-5

Significant user-visible changes

Distance matrices can be used instead of point patterns in Mhat, mhat and Kdhat and their envelopes.
The estimation of density used by Kd now includes reflection: the estimation of Kd is more accurate than before, but values may vary from previous versions close to the minimum distance.
LazyData is used to save memory.

dbmss 2.2-2

Minor change

Intervals of estimation of the Kd function are narrower when the distance range is small with respect to the window to improve precision.

Bug fixes

Distances pairs more than twice the maximum value of r where ignored when using the approximate estimation of Kd, so Kd was overestimated when r was smaller than usual (much less than the default values). Corrected.

dbmss 2.2-1

Bug fixes

Adjust argument ignored in Kdhat. Fixed.

dbmss 2.2-0

Significant user-visible changes

m function added.
Default value Controls=NULL for Dhat: controls are by default all points except for cases.

FillEnvelope returned wrong quantiles for local confidence intervals. Fixed.

dbmss 2.1-1

Kd is computed by default up to the median (instead of mean) distance between points.

Bug fixes

Kdhat with Reference and Neighbor points of different types was calculated with only half of point pairs and sometimes crashed R. Fixed.

dbmss 2.1-0

Significant user-visible changes

Kdhat and M are computed through C++ loops instead of spatstat pairdist(). Much faster, and uses far less memory.

dbmss 2.0-6

Significant user-visible changes
