Directory-based environment variable not properly set

Running the commands like Siyao did results in errors after installation of atime from GitHub, more specifically first not being able to obtain the environment variable for the current workspace (should be /home/runner/work/Autocomment-plot-GA/Autocomment-plot-GA for ${{ github_workspace }} and /__w/Autocomment-plot-GA/Autocomment-plot-GA for the checkout directory or${GITHUB_WORKSPACE} here), and then not being able to install the package correspondingly (tried to hardcode it with aforementioned values to get to this step, but it didn't work):

    - name: atime-step
      env:
        GITHUB_PAT: ${{ secrets.GITHUB_TOKEN }}
      run: |
        devtools::install_github("tdhock/atime@compare-dt-tidy")
        src_dir <- Sys.getenv("GITHUB_WORKSPACE")
        devtools::install(src_dir)
        options(repos="http://cloud.r-project.org")
        atime::atime_pkg(src_dir)
        shell: Rscript {0}

Run atime::atime_pkg(src_dir)

Running the statements together lead to errors as well:

Run Rscript -e 'devtools::install_github("tdhock/atime@compare-dt-tidy"); src_dir <- Sys.getenv("GITHUB_WORKSPACE"); devtools::install(src_dir); options(repos="http://cloud.r-project.org"); result.list <- atime::atime_pkg(src_dir)'
