[BioC] non appearing AffyIDs cColor

[Auer Michael]

Certain
affy IDS from the hgu133a chip, like 212094_at (PEG10) do not appeare on
the plot as bars.
I used the code
library(geneplotter)
library(hgu133a)
newChrClass <- buildChromLocation("hgu133a")
cPlot(newChrClass)
cPlot(newChrClass,scale=”relative”)

For example "212094_at" does not appear
cColor(”212094_at“, "green", newChrClass).
 I will attach a series of AffyIDS with there Nucleotide positions.
