Thans Dan. It seems that it may be an issue with 3.4.3...I'm going to attempt a patch this weekend. The code works fine from the command line in 3.2.5!

To be clear, I'm not really trying to save the OUTPUT of the file...it never even executes as far as I can tell. I'm calling it with C:\Program Files\R\R-3.4.3\bin\Rscript.exe "P:\Investments\Trading Tools\RV Tools\myfile.r" And again, it executes perfectly if I open the GUI first and then run it within R.

on Windows, anytime you send a path that contains a space to the command line it needs to be enclosed in double quotes.  Try a call like

"C:/Program Files/R/R-3.4.3/bin/Rscript.exe" "P:/Investments/Trading Tools/RV Tools/myfile.r"

I don't know how rscript handles the '\' character (i.e. as an escape or
not) so I changed the '\' to '/' just to be safe.  And note, the program pathname and the file being passed need to be quoted separately.

Hope this helps,
