[Tikzdevice-bugs] Running TikzDevice on Mac OS 10.6

[Cameron Bracken]

Hi Mike,

I use the same system.  Are you using the GUI?  The problem, I think, is
that the Mac GUI does not set the PATH completely.  What I suggest (this is
what I do) is create the file ~/.Rprofile and add the following lines:

Sys.setenv("PATH" = paste(Sys.getenv("PATH"),"/usr/texbin",sep=":"))
options(tikzMetricsDictionary = path.expand("~/.tikzMetricsDictionary"))

This will set the path to your latex compiler and also use a global metrics
file.  The advantage the second line is that tikzDevice will cache string
width calculations and access them later for speed.

Anyway, I suspect that this will fix your problem.

Cheers,
-Cameron
