Hi everyone, I have a matrix that contains 1000 replicates of a sample of a list of values. I want to group each row (row=replicate) into my defined bin ranges and then calculate the mean and stdev for each of the bin ranges (so I will have 1000 rows but ncol=number of bin ranges). I don't know how to group rows in a matrix matrix according to another vector (which is what I think I need to do).
Thanks for the help, Muri __________________________________________________ [[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.
