Hi all, I made the fatal mistake of updating affy after the devel version started requiring R >= 1.8.0 and before it actually became compatible with 1.8, so I am stuck in no-man's land (I realize I can use the release version, but I like some of the functionality of the devel version better). Is there some magical place on the bioconductor website (that I have yet to find) where I can get older devel versions of packages, or are they updated and the older versions simply vanish into the ether?
