[BioC] error retrieving normalized probe values from "pm" array

[Lana Schaffer]

Greetings again,
I was able to fix my last message by using options(scipen).
However, this call coversion to character is too time consuming.
pm(nbatch)[as.character(gene_indexes[[i]]),]
Is there a better way to retrieve the "pm" probe normalized expression 
values clustered by gene?
Thanks,
