Hi! I have Affimetrix data, but I don't have .CEL files, only a .xls. How can I open this file with Bioconductor? Thank you.

I would recommend search the R-help list for ways of reading .xls files in R. You might also try the RSiteSearch function in R. HTH, + seth

Depending on your OS, there are numerous ways to import the data. You can do one of the following, in order of simplicity: 1.) Save the .xls file as .csv and open using read.csv() 2.) If on Windows, access the data using the RODBC package 3.) Open the .xls file using Excel (or OpenOffice or StarOffice if on *NIX), copy the data, and import using scan("clipboard"). To be truly useful, this will require you to pass a list identifying the column type and probably wrap scan() in data.frame().
