How can I render a .R file in a random directory

Hello I would like to know how I can render a .R file so that all intermediary .Rmd and other temporary things are generated in a specific location ?
For instance I see a spin.Rmd and temporary html being generated.
I is annoying because

  • I use servr::rmdv2 to render continuously all Rmd from a directory and the temp Rmd created ‘interfere’
  • I’d like to be able to run render(‘my file.R’) from serveral processes with different arguments so I do not want things to clash

Can you give an example with code of your current workflow so that we could understand better ?

In rmarkdown, I believe you can use some argument in render to change the directories but I am not sure what you use. Is it knitr::spin instead ?

Thank you

I just use rmarkdown::render("my_file.R")
This will create a my_file.spin.Rmd intermediary file, I think render calls knitr::spin under the hood to transform the R file into a Rmd file

Yes it does.

This file is deleted usually. When I try I only get .R and .html at the end

You could try changing intermediates_dir = in render

Thanks intermediates_dir did the trick
