detritus NOTE when multisession plan declared in vignette

[tdhock]

Hi @HenrikBengtsson I had the following in my vignette

if(require(future))plan("multisession")

and that gave me the following NOTE when I checked the package on windows,

* checking for detritus in the temp directory ... NOTE
Found the following files/directories:
  'Rscript238c14018b99' 'Rscript2e8c14018b99'

which seems to be related to this post you made on R-devel, https://stat.ethz.ch/pipermail/r-devel/2021-June/080830.html
I got rid of the NOTE by putting the future code in a if(FALSE) but I was wondering if you ever got a response from R core about fixing that?

No reply. If you have the cycles, feel free to pick up that R-devel thread again.

PS. I'll migrate this issue to Discussions.

Make sure to read https://future.futureverse.org/articles/future-7-for-package-developers.html#making-sure-to-stop-parallel-workers

thanks, so the fix is:

To stop ‘multisession’ workers, call:
plan(sequential)
at the end of your examples(*), vignettes, and package tests.

Yes, this is the correct way per https://future.futureverse.org/articles/future-7-for-package-developers.html#making-sure-to-stop-parallel-workers.

(Sorry, I missed that the other user copy'n'paste your comment; not sure what that's about, so I'll probably clean up here and delete those comments)
