Thanks. But it seems to be an R 3.2.0 specific problem.

I replied with the following to a similar message on R-devel.

There was no error either with using help() or using the Mac GUI package manager. Those were the reported difficulties previously reported.

This may help.
Get R 3.2.0-patched or even the release candidate for R 3.2.1
????????????????????????

The error I am getting was from the most recent R 3.2.0 downloaded yesterday. 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.

Posting the session Info when running in the GUI

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

sessionInfo()

I had earlier tried following the code of help.search and its call to help by reading the code and running trace but was not able to find where the arguments of help.search had been renamed as ?topic?.

Then running in the Terminal window does not provoke the error.

I had earlier noted that the crash report for the launch of R 3.2.1 from the R.app (GUI) indicated that the directory that the GUI was attempting to load R from was incorrectly specified as: /Library/Frameworks/R.framework/Versions/3.3/Resources/
