I downloaded a GEO dataset with GEOquery and have my gse file turned into an ExpressionSet. I have two questions how to further proceed.
1) How can I get a table with all the gene expression levels?
2) How can I compare the Row labeling to the gene information from the CHIP that was used for the Assay? I know that there is a package for the CHIP infos that I need but I have no idea how to assign the gene names to the IDs.
I am not very familiar with R, so please excuse that my questions might be confusing.
Thanks a lot in advance!
