On reflection, it seems to me that what we really need here is Prof. Ripley's mind_read() function that was foreshadowed some years ago (see fortune("mind_read")) so that R could determine just *which* lm() (for example) function the user has in mind when he or she types ``lm(...)'' at the keyboard.
Perhaps Brian could report on what progress has been made with the mind_read() function. cheers, Rolf ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
