[BioC] ArrayQualityMetrics: Problem with labels in plots. A bug??

[Audrey Kauffmann]

Dear Jeremy,

Thank you for reporting this. You were right there was a problem in the 
code for the ordering of the colours.
I have now corrected it, so arrayQualityMetrics version 2.4.1 should be 
working fine.
Please let me know if you keep experiencing problems.

Best wishes,
Audrey
