(windows xp) start script on startup / double clicking on the script

hi,

I am still trying to figure out how it is possible to start an R- 
script via the R-GUI directly by double-clicking on the script file in  
windows xp.
On Mac OS I have the option "start script in the editor" in the  
preferences.

But on windows XP I always get the "ARGUMENT  'c:\...\...'    
___ignored___" error when I try to associate the .R extension with the  
R program file.

My problem is that I don't have the possibility to install any other  
programs.
And the people using the script don't know R.
So its really important to find a way to start a script just by double  
clicking on the file.

Now I was wondering if it is possible to make a shortcut of the R  
script and change the start options.
I am not familiar with windows - does someone know if that is a  
possible way to get R code to the R console (in the R gui) on startup?

Or any other clues / tips?

thanks for any help!

Re: (windows xp) start script on startup / double clicking on the script

Try creating a Windows batch file along these lines:

setlocal
set R_PROFILE_USER=C:\tmp\myscript.R
"C:\Program Files\R\R-2.9.x\bin\Rgui.exe"
endlocal

and double click it.  The set line sets it up to run your script and
the next line runs R.

Right you are Peter.  I just Googled the phrase and looked at the immediate context of the phrase, and not much
else of the document (since I was looking for a Kernighan reference).

There was actually a very recent discussion of this, and related operations.
See:

http://www.nabble.com/implementation-of-matrix-logarithm-%28inverse-of-matrix-exponential%29-ts25628876.html

Also, some good advice for finding a function when you don't know it's name
but you do know what job it performs is to have R search all the help pages
in all the packages you have using the ?? command:

??'matrix exponential'

You will see the expm() function in the base package Matrix if you have a
newish version of R.

Re: matrix exponential

RSiteSearch('exponential of a matrix')

      produced 982 matches. 

RSiteSearch('{exponential of a matrix}')

      produced 13.

  Remind me why this shouldn't just be done on the official R

Well... you could make a vector of the words you want to find:

to.find <- c( 'banana', 'peacock', 'Weapons' )

Read in the file...

file.text <- readLines( 'myFile.txt' )

And recursively apply the grep command in order to determine which lines
contain matches for your words:

line.matches <- unlist( lapply( to.find, grep, x = file.text ) )
