Hello,
I'm stuck trying to combine two different sets of samples from two different
exprSet objects into one exprSet object.

If I use cbind then I just get a matrix out.
gds1329Train <-
cbind(gds1329esetAT[,1:3],gds1329esetBT[,1:8],gds1329esetLT[,1:13])

If I use combine then this does not work
gds1329Train <-
combine(gds1329esetAT[,1:3],gds1329esetBT[,1:8],gds1329esetLT[,1:13])
Error in function (classes, fdef, mtable)  :
unable to find an inherited method for function "combine", for signature
"exprSet", "missing"

What I want is for gds1329Train to remain an exprSet so that I can use mfilt
on it.

any help much appreciated,
Best,
John
