Obtain statistics from a BSseqTstat object

Description

Essentially an accessor function for the statistics of a BSseqTstat object.

Usage

getStats(bstat, regions = NULL, ...)

Arguments

bstat	An object of class BSseqStat or BSseqTstat.
regions	An optional data.frame or GenomicRanges object specifying a number of genomic regions.
...	Additional arguments passed to the different backends based on the class of bstat; see Details.

Details

Additional argument when the bstat object is of class BSseqTstat:

stat

Which statistics column should be obtained.

Value

An object of class data.frame possible restricted to the regions specified.

Examples

if(require(bsseqData)) {
  data(BS.cancer.ex.tstat)
  head(getStats(BS.cancer.ex.tstat))
  reg <- GRanges(seqnames = c("chr22", "chr22"),
     ranges = IRanges(start = c(1, 2*10^7), end = c(2*10^7 +1, 4*10^7)))
  head(getStats(BS.cancer.ex.tstat, regions = reg))
}
