Can I use !# Rscripts in Windows

Question

In linux I used to put !#/usr/bin/Rscript so I can call myScript.R [options] on windows replacing the /usr path by the correct path C:/Program... does not work (nothing is happening). The only way I know is to do Rscript.exe myScript.R [options]. Is it possible to mimic the Unix behaviour ?

Answer 1

If you are using the default cmd.exe shell on Windows and are willing to use a second file then you can create a batch file, myScript.bat, containing this line:

Rscript.exe myScript.R %*

and then run it like this:

myScript

You can include arguments at the end of this line but they should not include embedded spaces.

Answer 2

Grothendieck is right. I'll show another idea to mix the two files.

rem <- function(...) invisible(T)
rem( '
Rscript.exe %~F0
EXIT /B
rem ')
### above=BAT, below=R

cat('Hello, World', file='hello.txt')

Save this as "hello.bat" and execute it. You can find more details in my blog.
