Hi,
First off, please don't take conversations off-list. The archives are
intended to be a resource for people to search, and if the conversation
becomes private that function ceases to exist.

Well you obviously have read the vignette, but evidently didn't
understand that there is just one step remaining. So here is an example:
library(geneplotter)
library(hgu133a.db)
## note that if you still have a package called hgu133a, then you
seriously need to update your R and BioC to the release versions.
newChrom <- buildChromLocation("hgu133a")
cPlot(newChrom, c(1:22, "X","Y"))
## Unless you like the extra clutter, I prefer to subset to non-random
chromosomes
## now fake up some genes - you of course would use the 100 that you are
interested in
gns <- sample(Lkeys(hgu133aSYMBOL), 100)
cColor(gns, "red", newChrom)
And that, I believe is what you wanted.
Best,
Jim
