R-3.0.1 (use all digits for describing an R version) is not the problem. Most likely you are masking a function or something like that. When you started the R session, did you get a message about "restoring a previous session"? If so, then close R, find the directory in which you were working and delete (or rename) the file ".RData", and start R again. Or perhaps you inadvertently detached the "stats" package. type "search()" to check on that. The repair is the same as above.
