Dear group, Apologies for asking the most chomped FAQ. I have a file with list of gene names(genes.txt): EGF EGFR PTPN6 TIEG2 MAPK1
I have another object in R, I do not know the data type for that object that looks like this ("lidnames"): "RABGGTA" "MAPK3" "TIE" "CYP2C19" > lidnames[1:10] 100_g_at 1000_at 1001_at 1002_f_at 1003_s_at "RABGGTA" "MAPK3" "TIE" "CYP2C19" "BLR1" I want to pick list of genes from lidnames object that are in genes.txt. I am using %in% function. >mygenes<-read.table("genes.txt") > mygenes[mygenes %in% lidnames] NULL data frame with 164 rows > I am unable to pullout genes from lidnames object. Is it because that lidnames is as a list type and mygenes object is as a vector/matrix type. How can I convert mygenes to list type where I can have the elements: "EGF","EGFR","PTPN6","TIEG2","MAPK1". I think in this way I can pull out the names from lidnames object or any other complex matrix. Please help me.
