Arghh!

In R GUI Sys.getenv("PATH") gives

[1] "/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin"


and in R in Terminal the same command gives

[1] "/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/usr/X11/bin:/Users/berendhasselman/bin"

Thanks. I did Sys.setenv(PATH=paste(Sys.getenv("PATH"),"/usr/texbin",sep=":")) in R GUI and now it works in R GUI and Terminal R.
