Hi, Can you please help me with using Oligo package. I am using Oligo Package to read celfiles. I donwloaded the data from GEOquery and now want to read the celfiles. But reading celfiles using read.celfiles gives an error. So I thought maybe its linked with the error that comes with loading the oligo library. I have included the code and the following errors. Code should be placed in three backticks as shown below

Loading required package: oligoClasses
Error: package or namespace load failed for ‘oligoClasses’:
 object 'maxindex' not found whilst loading namespace 'ff'
Error: package ‘oligoClasses’ could not be loaded

rawData<- read.celfiles(celfiles)
Error in read.celfiles(celfiles) : could not find function "read.celfiles"

I have installed oligoClasses but to no avail, It is still showing the same error above. I tried installing ff from CRAN but its not available for the R version I am using.

This type of error usually means that you are mixing Bioconductor packages from different releases. Try

BiocManager::version()  # Should be "3.12"
BiocManager::valid()  # should return TRUE, or installation instructions to make the  installation valid

ff is available under 'Windows binaries' at, so probably R is trying to tell you something else; posting the full installation attempt and message would help.
