How can we change Rscript to execute in 64-bit?
The following script prints "i386-apple-darwin9.8.0/i386 (32-bit)" :
#!/usr/bin/env Rscript
sessionInfo()$platform
I want to run RHadoop (rmr2) locally on Mac OS X 10.8.2 (Mountain
Lion) but it only works with Rscript in 64-bit mode.
Where is that one from (we can't tell?)
On a CRAN installation
/Library/Frameworks/R.framework/Resources/bin/exec/x86_64/Rscript
is 64-bit. And you can always run "Rscript --arch=x86_64" (not using
env, though).
