[BioC] arrayQuality - maQualityPlots - Error: duplicate switch defaults: 'list(dev =...' and ''

[Fabio Liberante]

Hello,

I've been trying to generate qualitative QC plots on a two-color set
of arrays using arrayQuality.
When I first generated the error I tried using the swirl dataset to
see if it was a problem with my data. The error still came up. It
seems that the dev switch is being set twice. I also tried setting
dev='png'/'pdf' etc., but still the same error. I looked through the
source of arrayQuality and I can't find any unclosed quotes that may
generate this error, but I could be wrong.

Any ideas?
