Hello,Dear Madam, Sir,I am a novice student of R, I'm in a training graduation and I encountered a problem on R (version 2.15.3) for the analysis of 'hugene21st' Affymetrix chips type; by installing the 'hugene21st' package with the controls:source ("http://www.bioconductor.org/biocLite.R")biocLite ("hugene21st")I have this error message: package 'hugene21st' is not available (for R Version 2.15.3) what to do to fix this problem pleas, or what version of R should be used to treat these chips. cordially; Chagdal Madiha SITN Master-2 : Statistics, Computer and Digital Techniques Claude Bernard Lyon-1 University [[alternative HTML version deleted]]

Hi Chagdal, One way to proceed is to start R in the directory containing your celfiles and then do biocLite("oligo") library(oligo) dat <- read.celfiles(list.celfiles()) eset <- rma(dat) then you want the hugene21sttranscriptcluster.db package to annotate: biocLite("hugene21sttranscriptcluster.db") Best, Jim On 6/14/2013 6:12 AM, chm chag wrote: > Hello,Dear Madam, Sir,I am a novice student of R, I'm in a training graduation and I encountered a problem on R (version 2.15.3) for the analysis of 'hugene21st' Affymetrix chips type; by installing the 'hugene21st' package with the controls:source ("http://www.bioconductor.org/biocLite.R")biocLite ("hugene21st")I have this error message: > > package 'hugene21st' is not available (for R Version 2.15.3) > > what to do to fix this problem pleas, or what version of R should be used to treat these chips. > > > > cordially; > > > > Chagdal Madiha > SITN Master-2 : Statistics, Computer and Digital Techniques > Claude Bernard Lyon-1 University > [[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor at r-project.org > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor -- James W.
