Puppet Class: r_lang

modules/r_lang/manifests/init.pp

Overview

SPDX-License-Identifier: Apache-2.0

Class: r_lang

Class containing stuff for installing R and its packages from different sources:

  • r_lang::cran for installing from Comprehensive R Archive Network (CRAN)

  • r_lang::git for installing from any Git repository (e.g. Gerrit)

  • r_lang::github for installing from a GitHub-hosted repository

Also provides a utility script for updating library of installed R packages.

Heads-up that by default r_lang::git and r_lang::github are technically not available because those require the R package 'devtools' which is not installed by default and cannot be installed because its dependencies are not installed unless the `$devtools$` parameter is set to `true`.

Parameters:

  • devtools (Any) (defaults to: false)
