p_load: Load One or More Packages

In pacman: Package Management Tool

Description

This function is a wrapper for library and require. It checks to see if a package is installed, if not it attempts to install the package from CRAN and/or any other repository in the pacman repository list.

Usage

p_load(..., char, install = TRUE, update = getOption("pac_update"),
  character.only = FALSE)

Arguments

char	Character vector containing packages to load. If you are calling p_load from within a function (or just having difficulties calling it using a character vector input) then pass your character vector of packages to load to this parameter directly.
install	logical. If TRUE will attempt to install a package not found in the library.
update	logical. If TRUE will attempt to update all out of date packages. Default allows the user to set a "pac_update" in his/her .Rprofile.
character.only	logical. If TRUE then p_load will only accept a single input which is a character vector containing the names of packages to load.
...	name(s) of package(s).
