I am getting the following error when trying to plot the coefficient of variance for a lumi expression et. plot(x.lumi, what='cv') Error in as.double(y) : cannot coerce type 'S4' to vector of type 'double' I have not had any problems creating the other QC plots that are recommended in the vignette. What could be causing this problem, or how can I diagnose it? thanks, Sebastien

Hi, Sebastien. You'll need to include the output of sessionInfo() and, ideally, a reproducible example in order to get a meaningful answer to your question. Sean
