addchr: Add 'chr' to GRanges seqnames

Description

addchr takes a loops object or GRanges object and simply adds 'chr' to seqnames

Usage

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

Arguments

dlo

A loops object or GRanges object

Value

• An identical loops object or GRanges object 'chr' added

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 add 'chr' to the first object

Examples

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