Hi, I would like to get in a unique chromosome plot both the data present in hg133a and in hgu133b. Since the geneplotter library needs a data package to build che chromosome location instance ChrClass.a<-buildChromLocation("hgu95av2") there is any way to combine the hgu133a and hgu133b data package?

Well, I do not think that there is anything automatic, but you should be able to do something like: 1) create one for each of your two chips 2) class?chromLocation gives: Slots: 'organism': Object of class "character". The organism that these genes correspond to. 'dataSource': Object of class "character". The source of the gene data. 'chromLocs': Object of class "list". A list which provides specific location information for every gene. 'probesToChrom': Object of class "genEnv". A hash table which will translate a probe identifier to chromosome it belongs to. 'chromInfo': A numerical vector representing each chromosome, where the names are the names of the chromosomes and the values are their lengths 'geneSymbols': An environment that maps a probe ID to the appropriate gene symbol So the important things are to merge the chromLocs, the probesToChrom and the geneSymbols (the other stuff had better be the same), and to then insert these back into the object. z <- buildChromLocation("hgu95av2") slotNames(z) > ml1 = z@chromLocs > names(ml1) [1] "1" "10" "10_random" "11" "12" "13" [7] "14" "15" "16" "17" "17_random" "18" [13] "19" "1_random" "2" "20" "21" "22" [19] "2_random" "3" "4" "5" "6" "6_random" [25] "7" "7_random" "8" "8_random" "9" "9_random" [31] "Un_random" "X" "Y" "X_random" "3_random" "15_random" These are not in any order, so you should just be able to make a new list that concatenates the values for each chromosome, then for probesToChrom stuff; > z@probesToChrom <environment: 0x3e8a628=""> w = as.list(z@probesToChrom) do the same for the other list, concatenate these and then do something like ne = new.env(hash=TRUE) z@probesToChrom=l2e(theconcatenatedlist, ne) and something not unlike that for the other part.... and you should be in business On Sat, Jul 24, 2004 at 03:58:06PM +0200, Raffaele Calogero wrote: > Hi, > I would like to get in a unique chromosome plot both the data present in > hg133a and in hgu133b. > Since the geneplotter library needs a data package to build che > chromosome location instance > > ChrClass.a<-buildChromLocation("hgu95av2") > > there is any way to combine the hgu133a and hgu133b data package? > > Raf > > -- > Prof. Raffaele A.
