I wanted to wrap this up, since I feel it's been resolved. R_HOME never did need to over-ridden by me, was not being over-ridden in spite of my attempts, and was never a factor during the long period when 'everything worked'.
In fact, my entire ordeal was caused by removing a comment from the rprofile.site file and in so doing, accidentally removing a closing brace from a function definition. In using a quick-and-dirty editor, this error wasn't highlighted. Having no output from rprofile whatsoever and no errors, I concluded it was not being run, and not being found. -- View this message in context: http://r.789695.n4.nabble.com/R-doesn-t-recognize-R-HOME-value-tp4637510p4638006.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
