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
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,
