Orchestrator that auto-installs the safe library layer: optional R packages,
Julia solver packages (via en_install_julia_pkgs()) when Julia is present,
and Python/Pyomo packages (via en_install_python_deps()) when Python or
conda is present. System software that is missing (Julia, Python, conda, GAMS)
is not auto-installed — the function reports it and points to the
platform-specific instructions printed by en_check_dependencies().
Arguments
- julia, python, r
logical. Whether to install each layer.
- recheck
logical. Run
en_check_dependencies()before and after.
