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 If TRUE will attempt to update all out of date packages.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
