Dear all, I am working with affymetrix data and I am writing a program in Perl to normalize the data. I would like to use some statistical formulas from R in my Perl program, some kind of interface. How can I do this? My second question is where can I find the R package translating the affymetrix cel files with the help of affymetrix cdf file. I know that I have seen a function like this in R but now I am not able to find it. Thank you, Pauline -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
