Hi, I am working with some R scripts that seem to call the older version of affy (maybe 1.0) and R 1.5.1. When upgrading the affy package to 1.1, I seem to have lost the ability to run older R scripts that use the affy 1.0 version. Is there an archive of R and affy that would allow users to keep using some of these older programs for scripts that are written specifically for these versions? Also, second question, are there scripts already written for R that will take affymetrix data from rma, and do MANCOVA with post-hoc group comparisons, and then make a tidy output of the results?
