[R] Trouble with .bat files upon installation of 15.0

[Sarah Henderson]

Hello to all --

I'm hoping that someone more knowledgeable than me can shed some light
on a problem I have been having. In point form:

- I am running XP on a 64-bit processor
- I run 5 automated R tasks every morning using .bat files and a
little utility called System Scheduler by Splinterware.  I cannot use
the inbuilt scheduled tasks functionality because IT won't let me for
"security reasons".
- Until June 8th I was running R 12.1
- On the afternoon of June 8th I upgraded to R 15.0 and removed 12.1
- I updated all of my libraries and ensured that old scripts were
running smoothly
- I updated the path to Rterm via the System control panel (C:\Program
Files\R\R-2.15.0\bin\x64)
- On the morning of June 9th my automated tasks all appeared to run
(according to System Scheduler) but none produced any results
- When I double-clicked the individual .bat files they all ran smoothly
- The same thing happened each day until yesterday when I broke down
and re-installed R 12.1 again and changed the path back (C:\Program
Files\R\R-2.12.1\bin\x64)
- Everything ran perfectly smoothly this morning

I confess that I am baffled.  As far as I am aware the System
Scheduler should simply act as a double-click on the .bat file at a
specific time, but there is obviously something more to it than that.
What have I missed?  I would like to get this sorted out, as I don't
want to have this stuff tied to 12.1 indefinitely, especially as I am
developing all new code in 15.0.

Thanks for any help you can offer,

Sarah
