It retrieves the nucleotide counts at each position and each strand and tests for differences between the two experiments with a likelihood ratio test using either a binomial or beta-binomial model. The statistic can be tuned across genomic sites by a shared Dirichlet prior.} \docType{package} \author{Moritz Gerstung, ETH Zurich, D-BSSE \email{gemoritz@ethz.ch}} \references{See our upcoming paper ...} \keyword{package} \seealso{\code{\link{deepSNV}}} \examples{## Short example with 2 SNVs at frequency ~10% regions <- data.frame(chr="B.FR.83.HXB2_LAI_IIIB_BRU_K034", start = 3120, stop=3140) ex <- deepSNV(test = system.file("extdata", "test.bam", package="deepSNV"), control = system.file("extdata", "control.bam", package="deepSNV"), regions=regions, q=10) show(ex) # show method plot(ex) # scatter plot summary(ex) # summary with significant SNVs ex[1:3,] # subsetting the first three genomic positions tail(test(ex, total=TRUE)) # retrieve the test counts on both strands tail(control(ex, total=TRUE)) ## Not run: Full example with ~ 100 SNVs.
