making barplots from multiple files in R
I am completely new to R, sorry for this basic question.
I have around 150 different csv files, in a folder. I am interested in two common columns with same headers, among the files and am trying to make bar plots for these two columns for all the files, separately.
Could any body please suggest how to do this in a loop? I make bar plot from a single file in following way.
a <-read.table(file="test.txt", sep="\t", header=T)
p_range<- range(a$cp,a$cm)
barplot(a$cp, ylim=p_range)
barplot(a$cm, add=T)

Hi Istvan,
Thank you for feedback. Sorry for posting something like this, I will search more and will discuss this problem in R forums. I face this issue while making density plots for small RNA occupancy at different loci. I thought if by any chance somebody might have done similar analysis and knew a better way do it. Thanks!
