Hi, I have a script to runs several .Rmd files and generates many pdf output files as a result. For each .pdf file that is generated, a .log file is also generated to to working directory. How can I control whether these log files are saved, and if they are, where they go? I'd prefer they go to a separate directory and not clutter the working directory, but can't figure out where to set this. Thanks!

Take a look at help(output_format); it appears it may be possible to redirect this kind of file away. I haven't tried it myself.
Are this log file, the latex log file ?
Because using pdf_document will give latex log file that are removed afterward if no error.
Are those files stating in your working directory ?

Yes, they look like latex log files (first line says "This is XeTeX, Version 3.14159265-2.6-0.99998 (TeX Live 2017) (preloaded format=xelatex 2017.5.23)") and they are staying in the working directory after the script finishes running. It used to be the case tat they are removed afterward, but not now. I wonder now if that's because there are numerous warnings of the type:
"Package microtype Warning: Unknown slot number of character
(microtype) \~A' (microtype) in font encoding TU' in inheritance list
(microtype) `microtype.cfg/358(protrusion)'.
"
I don't actually use the microtype package, so I couldn't figure it out, but maybe that's the way to dig to get rid of these log files. thank you!
Does the document renders ok ?
I think render(...., clean = TRUE) should delete those if everything results with no error. But they is maybe another option to change somewhere...

Thank you! still saves the output files (with the warnings only, no errors), so I'll keep digging. Thanks again.
If you can provide a reproducible example with this issue, I can try and dig with you.
