What I use is the latest version of R: rw2001. And I got the following
error message when I run RMA:

Error in sigToEnv(signature, fdef) : Trying to get slot "signature" from
an object of a basic class ("NULL") with no slots
In addition: Warning message: 
Incompatible phenoData object. Created a new one.
 in: read.affybatch(filenames = files)

Which information I should provide furthur or the latest version of R
has some bugs?
Thanks a lot!
