Is there a canonical method for calling R from MATLAB, on a Mac?

Rscript is a noninteractive variant of the standard R command, designed for just this use.

I've used Rscript with the --vanilla flag successfully from the OS X command line in the past. To use in MATLAB, this is what I'd consider doing.

1. Prepend the following to the top of myscript.R, the program you want to run:

   #! /usr/bin/Rscript

2. From the OS X shell, set the executable bit on your program if it hasn't been done:

   $ chmod u+x myscript.R

3. Now, you're set up to use the system function in MATLAB:

   >> system('~/path_to/myscript.R')

The usual caveats about paths apply.

Thanks. I'll try this. Hopefully it works as well as your git script, which I recently started using!

The statistics language, R, is not supported in MATLAB; however, the following link contains MATLAB functions on MATLAB Central and File Exchange that may allow communication from MATLAB to R.

Thanks for the reply, Doug, but that looks like a Windows-only solution.
