[BioC] Image function

[Joern Toedling]

Hi Priscila,

I am not completely sure what kinds of plots you want to generate, but 
you may want to have a look at the "image.RGList" function in package 
Ringo and, more general, at the package arrayQualityMetrics which 
generates diverse sets of plots for quality assessment of microarray 
data. Please read the manual pages of these two functions for details 
about how to use these functions with your RGList object. There are many 
other options for related plots in Bioconductor.
Hope this helps.

Regards,
Joern
