| That's the default filename if you open a PDF device. Open it
It's the default (and fallback) device and filename you fail to specify
something else. Ie 'Rscript -e "plot(1:10)"' will create it too.
My preferred alternative is to wrap call to plot() with actual device create
(something like 'if (!interactive()) pdf(my_filename, 8. 6)' with a
corresponding 'if (!interactive()) dev.off()' to ensure the file finalised
and close.
If we cannot (or do not want to) modify the given main.R, I would suggest
something along the lines of
Rscript -e 'pdf(myfilenamevar); source("main.R"); dev.off()' | tee
2024-07-28.log
and Bob's your uncle now in terms of how you spec the filename.
In short, I would let go of `R CMD BATCH` if it does not do what you want.
