   Why don't you use the Gene Annotation tool in EzArray? You don't even need
   to write any codes. Try it at [1]http://xulab.wisc.edu/ezarray/ (only guest

I want to annotate the gene symbols and other gene information for
affy chip hgu133a2. Tried many times but failed. Can you tell me how
I can finish it using limma or other packages in R?

Have you tried using the annotation package yet?


Here is another link to give you some directions about how to use
annotation packages in case you are new to this:


But if you have already tried these things, can you please tell me what
you have tried so far ( with results to a sessionInfo() in R) ? We even
have a posting guide to help you know what sorts of things to put into
your post here:


Maybe if I know a little bit more about what you are trying to do I can
help you out better. ;)
