I should have pointed out, as its not yet documented in batchfiles,
that the idea
is to copy RguiStart.bat to your %APPDATA%\Microsoft\Windows\SendTo
folder so that right clicking a folder in Windows Explorer and choosing
SendTo > RguiStart.bat will start up R in the folder that was right
clicked on.
No need to mess with the registry.

Of course if you have an .Rdata file in the directory then even that
is unnecessary
as you can just double click the .Rdata file to start R with that
.Rdata file loaded
(assuming you have allowed the R/.Rdata file type association when you
installed R -- if you did not then you can use the SendTo method with files
as well as directories).
