I am a graduate student and new to R and Bioconductor. I have been attempting to analyse microarray data from affymetrix rat gene 2.0 ST arrays in R. However, I encountered problems that suggest that 2.0 arrays have not been updated in Bioconductor (code and error message below).
I wonder if I can overcome this problem by installing the appropriate package? If not, please let me know if Bioconductor can currently be used to analyse rat 2.0 affymetrix arrays.
Thank you.
