Regarding where to save the jar file, you might be interested in "app dirs" (via tools::R_user_dir() in R from 4.0, the rappdirs package, the hoardr package) cf https://blog.r-hub.io/2020/03/12/user-preferences/#not-so-temporary-files3

So the suggested option would be to have a function, which 1) ask the user to create a directory in the home folder 2) download the jar file into that directory or, when no permission is granted, into the tmpdir() Thanks, no major changes necessary for that, Rainer > > Duncan Murdoch > > On 23/06/2020 8:18 a.m., Rainer M Krug wrote: >> Hi >> I have a package called `plantuml` (https://github.com/rkrug/plantuml) which >> converts plantuml code to UML graphs.
