R: Plot read profiles for a particular genomic region.
plotRegion
R Documentation
Plot read profiles for a particular genomic region.
Description
plotRegion plots the read profiles for a selected region. If SNPs is
set as 'TRUE', colored bars will appear indicating the ocurrence of SNPs at
each genomic position.
