[R-SIG-Mac] checking for pdflatex

[John Fox]

Dear all,

I've now implemented Simon's solution, setting the path in the .onLoad() function of the Rcmdr package and resetting it to its pre-existing value in .onUnload(). This seems to work fine for me and, I hope, will be a more robust solution.

Thanks again to everyone for their help.

John
