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.

I believe it is because we do not know the location of all genes. > hgu133aCHRLOC$"212094_at" [1] NA > hgu133aCHR$"212094_at" [1] "7" So our current version of the data packages > packageDescription("hgu133a")$Vers [1] "1.6.2" does not have this info (you did not say what version you are using), 1.6.4 is out for devel, and in it this particular affy ID is still not mapped. If you, or anyone else, knows of more up to date data please let us know as we would be very interested in updating this Robert > > _______________________________________________ > Bioconductor mailing list > Bioconductor@stat.math.ethz.ch > https://stat.ethz.ch/mailman/listinfo/bioconductor -- +--------------------------------------------------------------------- ------+ | Robert Gentleman phone : (617) 632-5250 | | Associate Professor fax: (617) 632-2444 | | Department of Biostatistics office: M1B20 | | Harvard School of Public Health email: rgentlem@jimmy.harvard.edu | +--------------------------------------------------------------------- ------+
