Thanks in advance for all help , I just started using R and have already done the following.
1. Read through multiple files to get input data 2. plot a vector (X say) 3. end Now i want to plot the vector X for different files on the same plot, and I don't know how to do that. One option I considered was to have a global data frame that holds X for each file. and then plot after iterating through the files. However I found that X has different lengths for different input files. Is there a cleaner way to do this Shank [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
