I used the function getProbeInfo from oligo package before and worked fine. I am trying to repeat the analysis but I get an error could not find function this is the script source("http://bioconductor.org/biocLite.R") biocLite("oligo") library(oligo) biocLite("pd.mogene.1.0.st.v1") library(pd.mogene.1.0.st.v1) geneCELs <- list.celfiles("D:\\c\\TCGA\\Data", full.names = TRUE) t<-read.celfiles(geneCELs) probein<-getProbeInfo(t, field=c('fid', 'fsetid', 'type'), probeType = "pm", target = "core", sortBy = "none") -- output of sessionInfo(): > probein<-getProbeInfo(t, field=c('fid', 'fsetid', 'type'), probeType = "pm", target = "core", sortBy = "none") Error: could not find function "getProbeInfo" -- Sent via the guest posting facility at bioconductor.org.

It's likely that you need to upgrade your R installation (and then install the latest oligo). b 2013/6/1 Shahenda El-Naggar [guest] <guest at="" bioconductor.org="">: > > I used the function getProbeInfo from oligo package before and worked fine.
