There was no error either with using help() or using the Mac GUI package manager.

There is no 3.2.0-Patched for Mavericks. The release candidate, R 3.2.1 RC, is marked on the ATT Research webpage as failing Make and it indeed fails to launch. I would NOT recommend that anyone accept that advice. But maybe it is a Mac-specific problem. When I remove the crippled R 3.2.1 RC and reinstall the R 3.2.0 and run from a Terminal window I do not get the help.search() error. So copying to R SIG Mac, and will not copy R-help on any further efforts. -- David. > > Berend > > >> On Sun, Jun 14, 2015 at 8:42 AM, David Winsemius <dwinsem...@comcast.net> >> wrote: >> >>> >>> On Jun 13, 2015, at 7:41 AM, Ramnik Bansal wrote: >>> >>>> Getting following error in using help.search >>>> >>>>> utils::help.search("linear models") >>>> Error in help(db[i, "topic"], package = db[i, "Package"], lib.loc = >>> lib, : >>>> 'topic' should be a name, length-one character vector or reserved word >>> >>> I first tried this in a Mac running the SL version for R 3.1.2 and did not >>> get this error.
