Description

This cookbook installs and configures R. It also contains an R_package provider which can be used in recipes to install R packages from CRAN.

Requirements

• apt: Required for APT installation.
• build-essential: Required for source installation.

Attributes

• node['R']['cran_mirror]: Used by the Rprofile.site template to set the system-wide default CRAN mirror.

• node['R']['version']: The R version to install. When using Apt, set to nil to always get the latest version.

• node['R']['config_opts]: Options to pass to R's configure script. Source install only.

Providers

R_package

The R_package provider can be used to manage packages available in the CRAN repository. Currently to use this provider, your default CRAN mirror must be set. The default recipe sets this for you.

Actions

• :install: Installs the package from CRAN. Does nothing if the package is already installed. [default]

• :upgrade: Upgrades the package to the latest version. Currently this will re-install the package even if it is at the latest version.

• :remove: Removes the package if it is installed.

Examples

Install a package:

R_package "snow"

Remove a package:

R_package "snow" do
    action :remove
end

Usage

Add the default recipe to the run_list of a node or role.
