I'll start by saying I am pretty much a beginner at this, and I'm pretty much going solo trying to learn data analysis using R. Currently I am working with an Affimetrix microarray dataset, more specifically their Human Gene 2.1 ST Array.
But apparently that was a very bad idea, as I'm facing a huge roadblock in trying to annotate the probe IDs properly. I've found annotation guides that cover all of their arrays but never specifically the human 2.1, and it is very frustrating. Even the Oligo package's (which is the package needed to analyze their data) actual guide wasn't helpful as it is badly formatted and parts of it are even cropped in the margin, making it impossible to follow.
After some searching, I found a product page for Human Gene 2.1 ST Array strip and they had some supplementary files that included annotation files in .csv
Now I need to import that file in an usable way into the R environment, and that's where I'm stuck now and could use some help. I know the right function to use would be "read.csv" but I don't know how to set it up in a way that it imports the file in the correct way without being completely broken.
