Dear List & Calin, I am trying to use Pathway Express from RontoTools for microarray analysis. I get the following error with keggPathwayGraphs command when I use the option "updateCache = TRUE". I want to use this option in order to download the latest KEGG pathways. Thanks & Regards, Shruti Marwaha Graduate Student Systems Biology and Physiology University of Cincinnati -- output of sessionInfo(): > library("KEGGREST") > library("ROntoTools") > kpg <- keggPathwayGraphs("hsa", updateCache = TRUE, verbose = F) NA element in edges.
