[R] open .r files with double-click

[stevenmh at muohio.edu]

Hi Folks,
On Windows XP, R 2.5.0.

After reading the Installation for Windows and Windows FAQs,
I cannot resolve this.

I set file types so that Rgui.exe will open .r files.

When I try to open a .r file by double-clicking, R begins to launch,
but I get an error message saying

"Argument 'C:\Documents and Settings\Zoology\My Documents\trial.r' _ignored_"

I click OK, and then R GUI opens, but not the script file.

Is there a way to change this?

thanks,
Hank
