build pkg down site from subdirectory on gh-actions

[floswald]

hi all

I have a non-standard setup for a research project where an R package is a subdirectory for a julia package. Both R and julia parts build their respective docs on the same machine, the julia command in the end copies the generated R HTML docs such that all is in one place. Yes it's a hack. It works locally though! it looks like this:

➜  LandUse.jl git:(master) ✗ tree -d
.
├── LandUseR
│   ├── R
│   ├── docs
│   ├── man
│   └── tests
│       └── testthat
├── docs
├── src
├── test

So, the package root contains the julia package LandUse.jl, and the R package is in the subdirectory LandUseR. There must be something in the gh-actions recipe that sets the root of the repo as the R-package root as well (maybe?), because I get this error

Run Rscript -e 'pkgdown::build_site(pkg = "/Users/runner/work/LandUse.jl/LandUseR")'
10
Error: Error: `pkg` is not an existing directory
11
Execution halted
12
Error: Process completed with exit code 1.

where this is my worklow file, and where I manually changed the pkg down command to run: Rscript -e 'pkgdown::build_site(pkg = "/Users/runner/work/LandUse.jl/LandUseR")' because it used to fail with "/Users/runner/work/LandUse.jl/LandUse.jl/LandUseR" not found. Any help greatly appreciated! thanks!
