How to match CHIP information about genes to feature data from downloaded GEO dataset in R?

Question

[lsbw]

Hi everybody,

I would like to analyze a dataset from GEO (GSE102133 or alternatively GSE102134). I downloaded the data and created an Expression Set and a matrix from my Expression Set. I am new to analyzing this kind of data in R and I am not sure how to match the features of my matrix to the gene information on the used CHIP. The corresponding CHIP info is: Human Gene 1.0 ST. I know that there is a package for R (pd.hugene.1.0.st.v1) but it only gives me the sequence infos. Do you have recommendations about an "easy" way to accomplish this? Thanks a lot!
