Languages management

Listing

You can manage several R and Python installations. Each app and each version of each app can be set to run with a specific R and/or Python version.

By going to Server then Languages from the Administration Panel, you can list all R and Python installations added to Apleno Server.

  • The Auto-detect will try to detect languages installed on your operating system and add them to the list. Please note that Apleno Server performs an auto-detect each time it starts;
  • The Add configuration will display a form to add a language by providing its path on the system;
  • For each language, you can:
    • Set as default to set this version as the default one for new apps. An individual app can still override this and use a different version;
    • Edit to change the language binary path;
    • Packages to manage packages;
    • Terminal to start a terminal;
    • Remove to remove this language.

Tip

Running Apleno Server in Docker? See R & Python versions for how to add another language version without rebuilding the image.

Packages management

You can manage packages from R and Python directly from the admin panel. The Packages option will lead to a page where you can install, update and remove packages.

  • The Add packages button will open a form to type package name to install. For R, you can also choose the CRAN mirror and the Library path;
  • The Add from file button will allow you to select a file containing a package for a local installation.

Terminal

Danger

Please be aware that only system administrators should have access to this, as a user with a terminal access can have great power over the entire server file system and can even execute commands on the server.

The Terminal option of a language will start a terminal to debug or make complex operations within a language installation.
