Hi, I was trying to map gene symbols to gene names using the org.Hs.eg.db package. I first convert the gene symbol to an entrez id, and then convert that to a gene name (example code below). However, during this process I can't get the gene names for some of the genes: -------------------------- library(org.Hs.eg.db) ### First two genes are ok... symbols <- c('JAK1','AATK','A2BP1','A2LD1') for(sym in symbols){ print('***') entrezid <- as.character(mget(sym,org.Hs.egSYMBOL2EG,ifnotfound=NA)) print(sym) print(entrezid) genename <- as.character(mget(entrezid,org.Hs.egGENENAME,ifnotfound=NA)) print(genename) } ------------------------- I don't get any gene names for the last two genes in this example. Is there a better way of doing this? Perhaps with some other function/package? thanks. [[alternative HTML version deleted]]
