Dear BioC,
I have five microarray datasets each with two levels. I'm plotting a
PCA figure and would like to avoid using color as page charges for
color in the journal I wish to submit are expensive.
Is there a way to turn the solid triangle symbol (pch=17) 180 degrees?
This would add enable me to use the upside down triangle (open and
solid) as another symbol set.
