...R yet. Instead, I have been making repeated function calls using a loop in Perl, to access other R and Bioconductor functions that I need such as t.test and ANOVA. This is very time-consuming, however. I am working in a Linux environment, and using R 2.1.0 Thanks for any help and suggestions!

...akes too much time(basically, I then need to read in values individually into R instead of as a 2D array, so the number of function calls from Perl to R is very large). Could you suggest another method whereby I could read an entire matrix or a file using an R function call? Thanks!

...ase tell me what the function is called, and how I can get hold of the code(since I believe affy only works on CEL files) ? I have downloaded the affy R code from Terry Speed's website already, but I don't know where (if at all) the code to perform PCA is. Thank you everyone!

...hich is what I had expected, after seeing the outputs in the case of simpler functions like sum. Could anyone please tell me how I can obtain the output I expect(i.e. the same as the command line output....giving values of t, p-value and the means)? Thank you very much for the help!!
