I thought that I should let everyone know that I have, in some sense at least, resolved my problem with 'no "doc" directory' and Rstudio. I got a useful reply off-list from Duncan Murdoch (thanks Duncan) to the effect that Rstudio requires its own purpose-specific binaries.
I was always under the impression that Rstudio would invoke whatever instance of R that the user had installed, but this seems not to be the case. Duncan pointed me to instructions for installing R in such a way as to satisfy Rstudio. I had not found such instructions previously. After considerable travail (I had "curl" problems with which I will not bore you) I managed to effect this installation, which put R into /opt/R/4.1.0 and lo and behold /opt/R/4.1.0/lib/R does indeed contain a "doc" directory (unlike, e.g. /usr/lib/R which is my non-Rstudio instance of R lives.) Having done that and having made the appropriate symbolic links, I was able to click on the Rstudio icon under Applications -> Programming and get Rstudio running. So far I can find no way to get Rstudio to do what I had hoped to be able to do --- something that cannot effectively be done in raw R. But that's another story. I raised this same issue on the "Rstudio Community" web site, and the contrast between what I got from that and what I got from R-help was striking. What I got from the former was deafening silence. I got seven responses on the R-help mailing list, plus Duncan's off-list response. Does this say something about the efficacy of mailing lists as contrasted with web site fora? Or is it just a difference between the R community and the Rstudio community? cheers, Rolf Turner -- Honorary Research Fellow Department of Statistics University of Auckland Phone: +64-9-373-7599 ext. 88276 ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
