Hi, I am learning Edge R and am having trouble importing data. I have to tab delimited files, each of two different time points I am trying to look at. How do I input these data into the edgeR program so that I can see the matrix? I hope this question makes sense.

Hello Audra, First things first, when reporting your session info, use use sessionInfo(), include the ( ). First, what are your tab delim files? is this RNA seq data, or some other form of count data. And most importantly what do you want to do in R. Before trying to do much analysis you may want to google some R starting guides to get learn a bit of the language, You will have a very hard time with edgeR if you don´t.
