sysreqs_install_plan {pkgdepends}

Create an installation plan for system requirements

Description

This function uses new_pkg_installation_proposal() and its methods to create an installation plan for one or more packages, and then print their system requirements.

Usage

sysreqs_install_plan(refs, upgrade = TRUE, config = list())

Arguments

refs

Packages to install.

upgrade

If TRUE, pkgdepends will choose the latest available versions of packages, instead of preferring binary packages over source packages.

config

Configuration options. See 'Configuration'. If it does not include library, then a temporary library is used, which is equivalent to not assuming any preinstalled packages. Pass sysreqs_platform here if you want a different platform than the one R is running on.

Value

List with entries:

• os: character string. Operating system.

• distribution: character string. Linux distribution, NA if the OS is not Linux.

• version: character string. Distribution version, NA is the OS is not Linux.

• pre_install: character vector. Commands to run before the installation of system packages.

• install_scripts: character vector. Commands to run to install the system packages.

• post_install: character vector. Commands to run after the installation of system packages.

• packages: data frame. Information about the system packages that are needed. It has columns:

  • sysreq: string, cross-platform name of the system requirement.

  • packages: list column of character vectors. The names of the R packages that have this system requirement.

  • pre_install: list column of character vectors. Commands run before the package installation for this system requirement.

  • system_packages: list column of character vectors. Names of system packages to install.

  • post_install: list column of character vectors. Commands run after the package installation for this system requirement.
