[R-SIG-Mac] Rscript on OSX

[Don MacQueen]

I'm a bit puzzled also. Rscript has been on my personal list of 
things to try out "some time soon" but I hadn't done so. Given Ido's 
question I decided to try it.

Is it somehow possible that the Rscript binary included with the CRAN 
binary installer is an intel binary, even though I installed on a ppc 
machine? See below for why I raise the possibility.


After installing R 2.6.1 from the CRAN binary installer, selecting 
default installation options, I get this:

[49]% Rscript --version
tcsh: /usr/local/bin/Rscript: Exec format error. Binary file not executable.

Command line R does work, and I get this:

>  sessionInfo()
R version 2.6.1 (2007-11-26)
powerpc-apple-darwin8.10.1

locale:
C

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base    

other attached packages:
[1] rmacq_1.0-1


I believe my R and Rscript are from the same binary install of R 2.6.1:

[51]% which Rscript
/usr/local/bin/Rscript

[52]% ls -l /usr/local/bin/Rscript
lrwxr-xr-x   1 root  wheel  53B Oct 18 07:25 /usr/local/bin/Rscript@ 
-> /Library/Frameworks/R.framework/Resources/bin/Rscript

[53]% which R
/usr/local/bin/R

[54]% ls -l /usr/local/bin/R
lrwxr-xr-x   1 root  wheel  47B May  3  2007 /usr/local/bin/R@ -> 
/Library/Frameworks/R.framework/Resources/bin/R



On the other hand, when I build R from source, Rscript does work:

[100]% ./Rscript --version
R scripting front-end version 42724



Thanks
