Check if installed packages have all their system requirementsSource:
sysreqs_check_installed() checks if the system requirements of all
packages (or a subset of packages) are installed.
sysreqs_fix_installed() installs the missing system packages.
NULL, then only these packages are checked. If a package in
packagesis not installed, then pkgdepends throws a warning.
Library or libraries to check.
Data frame with a custom print and format method, and a
pkg_sysreqs_check_result class. Its columns are:
system_package: string, name of the required system package.
installed: logical, whether the system package is correctly installed.
packages: list column of character vectors. The names of the installed R packages that need this system package.
pre_install: list column of character vectors. Commands to run before the installation of the the system package.
post_install: list column of character vectors. Commands to run after the installation of the system package.
The data frame also have two attributes with additional data:
sysreqs_records: the raw system requirements records, and
system_packages: the list of the installed system packages.
sysreqs_fix_packages() returns the same value, but invisibly.
These functions use the
sysreqs_platform configuration option,
man_config_link("Configuration"). Set this if
pkgdepends does not detect your platform correctly.
