In mg14/deepSNV-old: Detection of subclonal SNVs in deep sequencing data.

## 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. Requires an internet connection, but try yourself.
