On UNIX one can use #! notation. It would be nice to be able to do something
similar on Windows.
This could be done by giving Rscript the capability of skipping over
the first few
lines. For example, there might be a --skip=n argument or perhaps Rscript would
skip over any consecutive leading li
ActivePerl has '-x' switch which tells it to skip all lines in the file till
"#!".
This allows writing perl scripts in ordinary .bat files.
?shQuote contains a link with the following perl script example:
===8<===
@echo off
:: hello.bat
:: Windows executable Perl script
:: Note:
:: assumes perl
Good idea. ruby seems to work the same way. python does too but with
a slightly different definition:
C:\> ruby -h | findstr strip
-x[directory] strip off text before #!ruby line and perhaps cd to directory
C:\> perl -h | findstr strip
-x[directory] strip off text before #!perl line and
Haven't got any feedback on this one.
Will we be getting a perl/python/ruby style -x switch for Rscript for R 2.5.0?
It certainly would give more flexibility to users of Rscript on non-UNIX systems
where #! notation is not available.

I agree this would be a reasonable addition, but I wouldn't class it as
a serious deficiency, and I don't plan to wo
I think its best if core mods are done by the core group while others
focus on work that can be done external to the core.
Thus, what I have done is to enhance the batchfiles distribution with
3 new batchfiles: Rscript.bat, #Rscript.bat and runR.bat which will be

Fair enough, but then you also have to accept that the core group is
going to set the priorities. As far as I know *nobod
Surely R has higher standards than that. How about quality and
completeness of implementation?
Every other major scripting language has implemented this for good reason
and its a glaring omission.

Gabor, can we get a URL from you to a patch that implements this
functionality?

Just because its open source does not mean everyone should do everything.
I suspect I have more expertise in Windows batch than the core developers
and also suspect they have more knowledge of the core than I so its a
good division of labor if I provide the batch files and they add -x

I'd agree with this, as long as you don't limit it to the core
