For what it’s worth: I have the following code in the .First function in
~/.Rprofile:
(R 3.1.3 on OS X Yosemite)
if( .Platform$GUI == "AQUA" ) {
# this appends /usr/local/bin to what is already in PATH
# by default this is already in PATH (at least in 10.6.8)
# so remove any duplicated items
z <- Sys.getenv("PATH")
z <- unlist(strsplit(z,.Platform$path.sep,fixed=TRUE))
# add path to MacTeX executables for OS X Yosemite (which has a bug)
# in Terminal it is added automatically
z[length(z)+1] <- "/usr/texbin"
Sys.setenv(PATH=paste(z[!duplicated(z)],collapse=.Platform$path.sep))
}
Berend
