I just installed R on a Mac without any traces of earlier versions. It exhibited a well know problem:
WARNING: You're using a non-UTF8 locale, therefore only ASCII characters will work. Please read R for Mac OS X FAQ (see Help) section 9 and adjust your system preferences accordingly. The information needed is in section 7, not in section 9. ______________________________________________ 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.
