### Bootstrapping isolated, project-specific, and runtime-pure R setup via Nix ###

==> Existing isolated nix-R project folder:
 D:\temp\2025_01_21_12_45_16_1074\RtmpAnlJVpxlovk 

* current R session running outside Nix environment and not from RStudio

==> Added `.Rprofile` file and code lines for new R sessions launched from:
D:\temp\2025_01_21_12_45_16_1074\RtmpAnlJVpxlovk

* Added the location of the Nix store to `PATH` environmental variable for new R sessions on host/docker RStudio:
/nix/var/nix/profiles/default/bin

==> Also adjusting `PATH` via `Sys.setenv()`, so that system commands can invoke key Nix commands like `nix-build` in this RStudio session outside Nix[ FAIL 0 | WARN 0 | SKIP 36 | PASS 27 ]
