Sigh. Actually, when we last taught the course in Fall 2006, the version of R that students got in September was 2.3, since 2.4 came out in October. Having checked more carefully, the ReadAffy widget for phenoData or AnnotatedDataFrames (whichever was current) did *not* work in 2.4, but for a different reason. When the widget appeared and you pushed the button to "Read From File", you got the error message Error in new.env(hash = TRUE, parent = NULL) : use of NULL environment is defunct So, as far as I can tell, the last two "upgrades" of R/BioConductor have made the graphical interface in ReadAffy increasingly unusable. So, is there any chance that this will be made to work again some time in the (hopefully not too distant) future?
