Hi, Peng.  You will probably want to do some reading before posting.  There
is an entire manual on input/output with R available from CRAN that you
should read.

http://watson.nci.nih.gov/cran_mirror/manuals.html

Let us know if you have questions about reading .csv files after you have
read that manual.

As a recommended alternative, have a look at the package:

http://bioconductor.org/packages/2.4/data/annotation/html/mogene10stprobeset.db.html

Again, a simple search of the bioconductor metadata packages would have
turned this up.
