Hello, I am working with maQualityPlots. I would like to change colors of graphs of 'Spatial:Rank(M-Raw)' and 'Spatial:Rank(M-Norm)' from blue-yellow to green-red.I think I need to change col=NULL in : maQualityPlots(mrawObj, headerInfo = "", save = TRUE, dev = "png", col=NULL, badspotfunction=NULL, controlId = c("ID", "Name"), DEBUG = FALSE, ...) My question is: Where I can find information about the vector 'col' that would be helpful to change col=NULL? or may be I have to change qpImage(nbgraw, xvar = "maM", main = "Spatial: Rank(M-Raw)")? Sincerely, Natalia.
