[BioC] oligo package

[Shahenda El-Naggar [guest]]

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"
