Re: [R] Script auto-detecting its own path
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=)) If you use relative paths like so: # master.r source(AuxillaryFile.r) Then source(path/to/master.r, chdir = T) will work. Mastering working directories is a much better idea than coming up with your own workarounds.

Re: [R] Script auto-detecting its own path
in the package R.utils getAbsolutePath() or you can do a file.list(.. full.names=TRUE, recursive=TRUE,pattern=(.R)) the rest will require grep and pulling the file name and directory path apart If its not evident just ask and I'll write something for you. basically you want a call that returns the full path of a R script?

Re: [R] Script auto-detecting its own path
See findSourceTraceback() of R.utils, e.g. library(R.utils); example(findSourceTraceback); However, in general I would avoid using the above, because in nearly all cases there is a better solution which does not rely on knowing paths, e.g. setting up functions and calling those instead of using nested source() calls. Note also that I just fixed a minor bug, so make sure you install R.utils v1.7.3 or newer (on CRAN). /Henrik On Wed, Sep 29, 2010 at 5:01 PM, Stu Field s...@colostate.edu wrote: 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?
