[BioC] a question about how to use ChIPseqR

[wang peter]

hello all

i think the strandPileup function support both of data.frame and
readAligned object
as import data
so that is the coding

library(ShortRead)
library(ChIPseqR)
bamfile <- "nuclosome_MG.bam"
aln1 <- readAligned(bamfile, type="BAM")
counts <- strandPileup(aln1, chrLen=2e6, extend=1, coords="leftmost",
plot=FALSE)
Error in is.null(arg) : 'arg' is missing

R version 2.13.2 (2011-09-30)
Platform: x86_64-unknown-linux-gnu (64-bit)
