rmchr: Remove 'chr' from GRanges seqnames

Description

rmchr takes a loops object or GRanges object and simply removes the 'chr' from seqnames, if is present

Usage

rmchr(dlo)
## S3 method for class 'loops':
rmchr(dlo)
## S3 method for class 'GRanges':
rmchr(dlo)

Arguments

dlo

A loops object or GRanges object

Value

• An identical loops/GRanges object except 'chr' removed

Details

Often times, performing functions on GRanges objects can go awry if the seqnames are systematically different. A common example of this is when some GRanges objects has the format of 'chr1' while the other has '1'. We can remove 'chr' from the first object

Examples

library(GenomicRanges)
regA <- GRanges(c('1'),IRanges(c(36200000),c(36300000)))
addchr(regA)
regA
rmchr(regA)
regA
