[R-pkg-devel] Strange warnings from build

Hello All,

When I build my package.  I get the following warnings.  I think these are
related to LaTex and ElCapitan but are flowing through to my R build. All
the tests pass and the help files work.  These are just warnings but are
frustrating nonetheless.

Note: I just up graded to El Capitan OS - This blew out my Tex Maker / Knitr
to the point that I was ready to give up.  I had to uninstall mactex and
texmaker twice but everything seems to be  working okay as far a knitr and
Tex Maker is concerned - basically I can knit my document and get the same
results as before.

I am not sure where to start to correct the R build warnings and I have been
researching for about 2-3 weeks.  I am a little more fearful of the R build
warnings than the Tex Maker / Knitr as that issue was basically one of path.
In R build case I just don't know, so I am a little more fearful.  If
someone could give me a nudge in the right direction I would appreciate the
help.

Glenn

entries, and all their arguments documented.

Sorry, but I'm not programmed to handle this case;
I'll just pretend that you didn't ask for it.
