R help - Aug 2010 - Using command line --file or -f

*What I want to do:
*Create a windows shortcut that will start the R gui  **and**
simultaneously source a file

*What I have already tried:
*This almost works, but it's not the interactive R GUI:
     R --no-save --sdi -file="C:\SomePath\example.R"
These open the R GUI, but doesn't recognize -f --f --file -file
     RGUI --no-save --sdi -file="C:\SomePath\example.R"
     RGUI --no-save --sdi -f "C:\SomePath\example.R"
     I've thought about suppressing the error and then parsing
commandArgs()...
     Although this may be possible, it seems preposterously overly
complicated.

*My last resort:
*   Having an entire installation of R with a "Rprofile.site" that
will
source my program.  The whole installation would be devoted to just running
that one program.  I think it will work, but it's an annoying waste of
space, and confusing to have multiple R installation.


Thank you very much!


What I'm using:
   Right now, R 2.10 on Windows 7, but I'm happy to use any version.  My
intended audience will be using Windows 7

I've spent a fair amount of time searching the online help using my favorite
help sites:
http://r-project.markmail.org/
http://r.789695.n4.nabble.com/R-help-f789696.html

I've also looked at the PDFs that come with r, especially the R-intro (which
is where I got the --f and --file ideas).

Sometimes I see help responses that just point to the chapter of a book, or
a PDF on Cran.  I would be delighted to discover my own answer in the
available materials, but please give some hint about why the cited material
is relevant!

Shouldn't that be --file=... (i.e., with 2 dashes)

Which error?  I don't see one.

I don't have Windows to test on, so this is a shot in the dark.
Do you have to double-backslash escape the file path?

Can't you set the file associations to start up RGUI when you launch  
an .R file?

Isn't there a Google Code project that handles windoze stuff like this?

http://code.google.com/p/batchfiles/

RGuiStart.bat   # perhaps?

Cannot test because I haven't used R on PC's for the last two years.

A much simpler approach would be to create a script file of some sort 
that takes the name of the file, sticks it into the environment variable 
  R_PROFILE_USER, then starts Rgui.  If you've already got a user 
profile set, then I think you'll need to use one of your more elaborate 
schemes.   I'd put the filename onto the Rgui command line after --args, 
then my user profile would use commandArgs() to check to see if anything 
was there and would source it.
