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 barplots for these two colums for all the files, separately.
Could any body please suggest how to do this in a loop. I make barplot from a single file in following way.
>a <-read.table(file="test.txt", sep="\t", header=T)
> p_range<- range(a$cp,a$cm)
