Possibly you can use the rappdirs location *if it exists* and tempdir()
otherwise. You could make the rappdirs location when running the shiny
app. Since the user has to do something to run the app, this is probably
ok. I think the problem is that loading the package itself cannot result
in a data download outside tempdir().
Best,
Greg.

Thanks for the tip with rappdirs.
I am just not sure, how I should handle the questions, as it should
also run in a shiny application?

I use rappdirs to construct a platform appropriate consistent package
download directory. But for CRAN I believe you will need to obtain
some kind of user confirmation at least once to allow this behaviour.
Best, Greg.

Hi
I am writing a package which downloads files which become part of
the package (only useful for functions in the package and
independent of the working directory) into
system.file("installedSchemes", package = "dmdScheme")
(See
https://github.com/Exp-Micro-Ecol-Hub/dmdScheme/blob/b97e7b5ef116476e065aeec1da1050eecbd6adf7/R/scheme_install.R#L71-L75
for the function).
I know that is regulated for R packages, but I can’t find it.
Is this allowed for R packages? Will this be allowed for CRAN?
I would prefer not to allow custom paths here, as it would
complicate things.
Thanks,
Rainer
