Description

Produces a plot with all chromosomes for a given organism, marking regions of interest in a user-specified color.

Usage

plotChrRegions(regions, chrLength, markColor='red', ...)

Arguments

regions

RangedData object with chromosome, start and end positions (chromosome must be stored in space(regions).

chrLength

Named integer vector with chromosome lengths in base pairs.

markColor

Color to be used to mark the regions in the chromosome.

...

Further parameters passed on to plot.

Value

This function produces a plot.

Examples

set.seed(1)
chr <- rep(c('chr1','chr2'),each=10)
chrLength <- c(chr1=10000,chr2=5000)
st <- c(runif(10,1,10000),runif(10,1,5000))
regions <- RangedData(IRanges(st,st+50),space=chr)

plotChrRegions(regions,chrLength=chrLength)
