[BioC] combineAffyBatch problem

[Flora Fan]

Dear Robert, Wolfgang and Bioconductor people,

I tried to use the combineAffyBatch function, by typing

> new<-combineAffyBatch(list(U133Adata, U133plus2data), c("hgu133aprobe",
hgu133plusprobe"), newcdf="comb", verbose=TRUE)

then it gave me:

package:hgu133acdf hgu133acdf
package:hgu133plus2cdf hgu133plus2cdf
24828 unique probes in common

But after that the prompt never shows up, what could go wrong?
Any suggestion would be appreciated.

Flora
