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
