rmchr {diffloop} | R Documentation

## 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)

    ## S4 method for signature 'loops'
    rmchr(dlo)

    ## S4 method for signature 'GRanges'
    rmchr(dlo)

### Arguments

`dlo` | A loops object or GRanges object

### 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

### Value

An identical loops/GRanges object except 'chr' removed

### Examples

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