Dear virtualArray maintainer, I'm facing the following problem. When I run "virtualArrayExpressionSets" on a few expression sets in a clean R session it works fine, but if I'm running the function again the exact same way in the same session it gives me the following error: ##Error """ Error in LastError$store(results = results, is.error = is.error, throw.error = TRUE) : Errors occurred during execution. First error message: Error in as.character.default(x): no method for coercing this S4 class to a vector """ ##Code for calling the function data.combined <- virtualArrayExpressionSets( all_expression_sets=c(eset.A,eset.B,eset.C,eset.D), identifier = "SYMBOL", collapse_fun = median, removeBatcheffect = "EB", sampleinfo = FALSE) I'm probably overlooking something obvious, so any comments are much appreciated. Thanks a lot!
