Hi, I am using KEGGprofile to perform KEGG enrichment for a non model organism. Using the data from the R documentation i perfectely obtaine the enrichment. >data(pho_sites_count) >genes<-names(rev(sort(pho_sites_count[,1]))[1:300]) > summary(genes) Length Class Mode 300 character character > is.vector(genes) [1] TRUE >pho_KEGGresult<-find_enriched_pathway(genes,specis='hsa') However, when I use my datasets, which I submit as character vector with NCBI ID, I get the following error: Error in phyper(kegg_result_length[x], keggpathway2gene_length[x], length(unique(unlist(keggpathway2gene))) - : Non-numeric argument to mathematical function Any suggestion how to overcome this problem? Thank you very much. [[alternative HTML version deleted]]

Dear Stafano, I think the ID from the non model organism may cause the error. Would you please tell me the specie you tested and send me some of your genes. So that I can have a try. Thank you!
