Any time you see an error like that, it means that you haven't yet loaded the package that has that function. So you need to first load the package using library().

I also faced another problem with a mark "=" ,, like this command below:

> plotAffyRNAdeg(deg,col=cols)
> legend(legend=sampleNames(dat), x="topleft",
+ + lty=1, cex=0.5, col=cols)
Error: unexpected '=' in:
"legend(legend=sampleNames(dat), x="topleft",
+ lty="

what about it ??
