Hadley,
I'm not sure this will solve the issue because if I move the script, I would
still have to go into the script and edit the "/path/to/my/script.r", or do I
misunderstand your workaround?
I'm looking for something like:
file.path.is.here("myscript.r")
and which would return something like:
[1] "c:/user/Desktop/"
so that regardless of where the script is, as long as the accompanying scripts
are in the same directory, they can be easily sourced with something like:
dirX <- file.path.is.here("MasterScript.r")
source(paste(dirX, "AuxillaryFile.r", sep=""))
Thanks,
Stu
