[R-SIG-Mac] Does anyone recognize this error?

[Bryan Hanson]

[a variation of this was posted on r-help the other day with no answers]

I've done something to my installation and can't find the cause.  This started up a few days ago, it could be related to the problem that Simon was working on in the past 48, but I increasingly think not.

My current install is totally fresh this morning off of r.research.att.com and the problem persists.  Here's a couple of examples:

Example 1:
> ?sd
Error in help("sd", package = NULL) : 
  could not find function "%is.not.a%"

Example 2 (from r-help posting):

I have 3 packages that I authored and they build and check just fine locally.  However, when I try to install the local source packages (from the .tar.gz), I get the following message: 

Error in `+.POSIXt`(as.POSIXct(origin, tz = tz, ...), x) : 
  could not find function "%is.a%" 
In addition: Warning message: 
In install.packages(file.choose(), .libPaths()[1], NULL, type = "source") : 
  installation of package ‘/Users/bryanhanson/Documents/Research/MetabolomicsProjects/ChemometricsStuff/BAHpackages/FuncMap_1.0-1.tar.gz’ had non-zero exit status 

Now this is pretty surprising to me; I don't use this function or any having to do with times or time series.  I get the same message no matter which of the 3 packages I try to install locally.  Further, if I go looking for whatever this function is, the following occurs, and no browser window opens: 

> findFn("is.a") 
found 3 matches 
Error in stopifnot(x %is.a% "POSIXct") : could not find function "%is.a%" 

Which is the same error as one gets just asking for help (Example 1), so I think that error is superceding any display of help pages.

And a google search of the error message doesn't produce anything recent. 

Does anyone recognize this problem/error?  I've thrown out and re-installed several times and it persists.  I feel like it might be in a hidden file (I have not yet tried to remove all existing .Rhistory files).  I also had a development version of ggplot2 installed a few days ago, in an attempt to fix a different problem.  My current sessionInfo() is below.

Thanks for any suggestions about where to look.  Bryan
