Hi , I was trying read in an affy array/matrix and then to calculate the mean value for all the duplicates. Is there a function in the R package that would do this? I tried the help function and searched for 'duplicate'. Although it provides a list of functions that would eliminate the duplicate probe ids, I couldn't find one that would calculate the mean for the duplicates. Any help would be appreciated. thanks. __________________________________________________ [[alternative HTML version deleted]]
