Dear Wolfgang,
Sorry for the incomplete email; I (incorrectly) thought there was a
problem with the exprs() function and thus minimised the example.
Here's the code following the virtualArray vignette:
library("GEOquery")
GSE13507 <- getGEO("GSE13507",GSEMatrix=FALSE, AnnotGPL=FALSE)
summary(exprs(GSE13507))
Error in (function (classes, fdef, mtable) :
