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? > > 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 > > > > > On 29 • Sep • 2010, at 15:23, Hadley Wickham wrote: >>> >>> Forgive me if this question has been addressed, but I was unable to find >>> anything in the r-help list or in cyberspace.
