Packages in an R-universe

List all packages available in an R-universe.

runi_packages(universe, package = NULL, version = NULL)

Arguments

universe	A length one character. User or organization name of the the R-universe owner.
package	either NULL, or a length one character. Package name (see details).
version	either NULL, or a character vector. Package version (see details).

Value

a tibble if both package and version are not NULL, a character vector otherwise.

Details

This function gives access to three types of information, depending on how many arguments are different from NULL:

• runi_packages(universe) lists all packages in the R-universe universe.

• runi_packages(universe, package), where package is a string, lists all available version for package package in this universe.

• runi_packages(universe, package, version) lists all available builds for package package of version version (specified as a string).

The argument version is ignored if package is NULL.
