Hello, I’m getting an error message when trying to run csHeatmap from CummerBund. All other functions are working fine so I’m thinking that a required package is not being loaded and the function is not available it. Any thoughts on what that might be. I’m not seeing any documentation out there that has this specific problem. The error seems to be common but I can’t find the package that might not be there. All other required packages (from the documentation) have been installed. Thanks, todd R code: library(cummeRbund) cuff <- readCufflinks(dir=cuff.dir) features <- cuff@isoforms features h <- csHeatmap(features, cluster='both') h Output (Error is at the end): Loading cummeRbund...
