[BioC] I would like to know how to run PRvQCHyb in arrayQuality

[Wonjong Moon]

I would like to know how to run PRvQCHyb in arrayQuality. I copied four
gpr files into a same directory. They were from the same print run.

PRv9mers() worked fine, but PRvQCHyb () had 'invalid regular expression'
error.
If I specified one file name, then it generated only one picture file
with the file size 0 and subscript out of bounds error. Could you help
to use PRvQCHyb? 
Thank you.
