Hello everybody, I just started using R for my microarray analysis, so I am quite new to all of this. For now I have done preprocessing, normalization, limma and globaltest KEGG pathway analysis.
I would like to see how each in gene in a certain pathway contributes the significance of the pathway. Therefore, I would like to combine the output of limma analysis and the genes that belong to a certain KEGG pathway. It is simple to get a list of genes that belong to a pathway in a vector, but I dont know how to pick only those genes from the limma toplist-file, with all the belonging statistics and make a new datamatrix from that. I hope my story is a bit clear, cause I dont know the exact R terminology. I have googled this, read many online introductions to R, but I cannot find it. I hope I havent posted this in the wrong place, but I hope that their is someone who can help me. Is there a function that is capable of picking only those elements from a datamatrix that correspond to the elements of a list? That's basically what the question comes down to. Many thanks!
