Hi, I'm a new user to Bioconductor.

I'm trying to get the array quality for .gpr files for Operon Version 3
mouse oligos. using arrayQuality

when I typed
> gpQuality()

give me error message:
[1] "Starting gpQuality..." Error in median(emp, na.rm = TRUE) : need
numeric data

Does anybody know how to fix it?

Thanks a lot!
