In geneXtendeR: Optimized Functional Annotation Of ChIP-seq Data

Description

Makes bar graphs showing the number of genes under peaks at various upstream extension levels.

Usage

barChart(organism, start, end, by)

Arguments

organism	Object name assigned from readGFF() command.
start	Lower bound of upstream extension.
end	Upper bound of upstream extension.
by	Interval between consecutive extensions.

Value

Creates bar charts.

Examples

library(rtracklayer)
rat <- readGFF("ftp://ftp.ensembl.org/pub/release-84/gtf/rattus_norvegicus/Rattus_norvegicus.Rnor_6.0.84.gtf.gz")
fpath <- system.file("extdata", "somepeaksfile.txt", package="geneXtendeR")
peaksInput(fpath)
barChart(rat, 1000, 3000, 100)
