Hi, all, I wrote the command:library() and can find the package GenePattern available: GenePattern ** No title available (pre-2.0.0 install?) ** However, it cannot work, just like as below, when writing the command: library(GenePattern) Error in library(GenePattern) : there is no package called 'GenePattern' The manual of GenePattern software says: If you are using a version of R which you cannot modify (because it is a publicly-shared version and you don't have appropriate privilege), you can have it load the GenePattern library by setting the environment variable R_LIBS=GenePattern install directory>/R/library in your autoexec.bat, .cshrc, .bashrc or other shell startup file. R will then load from its usual location, but will also search for and find the GenePattern library from your installation. I am a new user to R(OS: WINDOWS XP), and didn't understand the words and know how to run the procedure. Any suggestions and advice will be appreciated. I am looking forward to your reply.

So I would recommend: 1. Update R to the latest stable release: R 2.1.0 2. Reinstall GenePattern (which is not a Bioconductor package, BTW, so I'm not sure if this is the best place to ask for GenePattern specific help. + seth
