[BioC] affyPLM query

[Caroline Johnston]

Hi,

If I have a pset object (from fitPLM()), I know I can do something like

image(pset, which=2)

Is there a way to do the same thing, but indexing on chipname (ie. the
colnames from the expression matrix of the AffyBatch)? Along the lines of,
image(pset, which="chipname")?

Many thanks,

Cass.
