[BioC] Combine function in matchprobes

[Tan, MinHan]

Hi,
 
I tried combining 2 Affybatches (HGU133A and HGU133Plus 2.0) using
combine in matchprobes, but ran into the following problems.
 
I used both R 1.9.0 and R 1.8.1 with the latest downloads from
Bioconductor.
 
> merged.data <- combine(list(DataHGU133A,DataHGU133P), c("hgu133acdf",
"hgu133plus2cdf"), "mycdf", verbose=TRUE)
package:hgu133acdf      hgu133acdf      
package:hgu133plus2cdf  hgu133plus2cdf  
0 probes in common between hgu133acdf and hgu133acdf 
Error in sequs[[i]] : subscript out of bounds
 
Looking at the combine function, I seem to be running into problems at
this point? 

> tmp <- get(upp[1], uppname[1])
> str(tmp)
length 0 <environment>
> upp[1]
[1] "hgu133acdf"
> uppname[1]
[1] "package:hgu133acdf"

 
Your advice is very much appreciated!
