[R] Opening Rgui by double-clicking R script

[Sundar Dorai-Raj]

Hi, all,

This is for R-2.5.0 on WinXP and in particular RGui.

I'm trying to teach some colleagues of mine R and rather than impose 
Xemacs/ESS upon them I decided to simply start by showing them RGui. 
When R is installed, R workspaces (.RData) are automatically registered 
so that I can double-click on them in Explorer RGui opens with the 
correct working directory. However, I cannot figure a way to do the same 
for R scripts. In other words, I want to double-click on a .R file in 
Explorer, have RGui open, set the working directory to the location of 
where the script is saved, and load the script into the script editor. 
Is this possible?

Thanks,
