[BioC] Error with arrayQuality

[Shripad Sinari]

Hi,

I get the following error when running gpQuality

 > gpQuality()
[1] "Starting gpQuality..."
Error in if (skip > 0) readLines(file, skip) :
    missing value where TRUE/FALSE needed
In addition: Warning messages:
1: input string 30 is invalid in this locale in: grep(pattern, x, 
ignore.case, extended, value, fixed, useBytes)
2: input string 30 is invalid in this locale in: grep(pattern, x, 
ignore.case, extended, value, fixed, useBytes)

The following is package description on my machine:

I have faced the same error with agQuality but not with maQualityPlots 
functions. I suspect this is file reading error.

Thanks for the help,
