This should work fine if pdflatex is in /usr/texbin, which I now understand is by far the most common case (and is the case on my Mac). Do you mind if I adapt your code for the Rcmdr? I can fix the path in this manner at startup of the Rcmdr GUI and restore it to its initial value on exit from the GUI.
