[R-SIG-Mac] Rscript?

[Kevin Ushey]

FWIW, with a recent-ish CRAN R installation (3.2.2 patched, r69059) on
El Capitan, I have the same and all is well:

    kevin:~$ which Rscript
    /usr/local/bin/Rscript

    kevin:~$ which Rscript | xargs greadlink
    /Library/Frameworks/R.framework/Resources/bin/Rscript

    kevin:~$ which Rscript | xargs greadlink -f
    /Library/Frameworks/R.framework/Versions/3.2/Resources/bin/Rscript

Is it possible that the 'Current' symlink in your Versions folder is
not up to date for some reason? (You should see a number of installed
R versions in `R.framework/Versions/`, with `Current` being a symlink
to the currently active version of R).

It might be useful to see the output of `ls -la` in both your
R.framework and R.framework/Versions folders, to confirm.
