There are many similarities with this post:
R command line passing a filename to script in arguments (Windows)
Also this post is very OS related. My answer applies only to Windows.
Probably what you are looking for is RScript.exe
instead of R.exe
. The latter has no problem with spaces: path\to\RScript "My script.r"
.
One boring thing may be searching or setting the path for RScript
and doing this every time one updates R.
Among the convenience scripts I have in my search path, I wrote a little facility to run RScript without bothering with paths. Just in case it may be of interest for someone:

The script prints the actual RScript invoking line, before running it.
Note that there is an added argument, -cd
, to change automatically to the script directory. In fact it is not easy to guess the script path from inside R (and set it with setwd()
), in order to call other scripts or read/write data files placed in the same path (or in a relative one).
This (-cd
) might possibly make superfluous your other commandargs, as you may find convenient calling them straight from inside the script.
