Hello All, I am new to R and want to use R to scale my data before analysis. I need to do two fold scaling: a). scale on a per object (chip) basis, scale to a mean of 0 and stddev to 1; b). scale on a per feature basis: scale data linearly to the interval [0,1]. Could somebody help me with this? Thanks a lot, Jas __________________________________

Jas, You should look into using bioconductor (http://www.bioconductor.org), a group of over 65 R packages for dealing with all aspects of microarray analysis. There are numerous functions in those packages dealing in multiple ways with your problem. Sean
