#7 latex/pdflatex is not found when using R.app

[Cameron Bracken]

This is not an issue caused by pgfSweave. Since pgfSweave() sets environment variables PDFLATEX='pdflatex --jobname=<jobname>', /usr/texbin needs to be in the path. This works fine in the command line interface and when using R CMD pgfSweave but not in R.app. This possibly may not work in the windows gui either. A more general way of getting this to work is desirable.
