p_boot: Script Header: Ensure 'pacman' is Installed

In pacman: Package Management Tool

Description

Generate a string for the standard pacman script header that, when added to scripts, will ensure pacman is installed before attempting to use it. pacman will attempt to copy this string (standard script header) to the clipboard for easy cut and paste.

Usage

p_boot(load = TRUE, copy2clip = interactive())

Arguments

load	logical. If TRUE ; library(pacman) is added to the end of the script header.
copy2clip	logical. If TRUE attempts to copy the output to the clipboard.

Details

The script header takes the form of:

if (!require("pacman")) install.packages("pacman"); library(pacman)

This can be copied to the top of scripts to make it easy to run scripts if the user shares them with others or to aid in long term script management. This may also be useful for blog posts and R help sites like TalkStats or StackOverflow. In this way functions like p_load can be used without fear that others don't have pacman installed.

Value

Returns a script header string (optionally copies to the clipboard).

Examples

p_boot()
