Hi everybody, I just started my phd thesis and my aim is to analyse microarrays. Now I'm trying to analyse them with R (1.7.1). I use the limma package and my data are created with imagene (.txt files). And I'm not able to make R understanding what I mean. I know, I have to make a matrix, but I don't know, how I can put my data in this matrix. Maybe someone can help me with this problem, so I can go on with my work? Would be great. Thanks a lot, Karin.

Its not really clear what you are asking here, but try looking at the help files for limma. You should probably start with the help for read.imagene, which is a function to read your data into an RGlist for further analysis. You might also try looking at the limma users manual, which can be found by typing help.start() in R, then clicking on Packages --> limma --> Accompanying documentation --> usersguide.html HTH, Jim James W.
