Hi,

I'm having some issues running the "hyperGTest" function from GOstats. I get the following error:

Error in initialize(value, ...) : 
  invalid names for slots of class “GOHyperGResult”: pvalues, oddsRatios, expectedCounts, catToGeneId, organism

Here the code I use:

library( GO.db)
library(org.Dr.eg.db)
library (GOstats)

pCutoff <- 0.05
params <- new("GOHyperGParams",
               geneIds=commonGenes,
               universeGeneIds=BPA,
               annotation= "org.Dr.eg.db",
               ontology="BP",
               pvalueCutoff=pCutoff,
               conditional=FALSE,
               testDirection="over")

GOHyperBP_over <- hyperGTest(params)
