How do I fix this? When I reinstalled the latest versions, all that's contained in /usr/local/lib/R/library/affy/R-ex/plot.Probeset.R is: ----------------------------------- ### Name: plot.ProbeSet ### Title: plot a probe set ### Aliases: plot.ProbeSet ### Keywords: hplot ### ** Examples data(SpikeIn) plot(SpikeIn) ----------------------------------- Help?
