Dear Bioc,

I am using the package GSEABase, and I have the following error.
I imput eset in the function GeneSetCollection, but I do retrive the
following error. I am using Illumna datata,
and transformed the lumi.batch in expression set.

> gsc <- GeneSetCollection(eset,
+    setType = KEGGCollection()
+ )
Error in validObject(.Object) :
  invalid class "ScalarCharacter" object: ScalarCharacter must have length
one

thank you
