In previous posts I described how to input data stored on GitHub directly into **R**.

You can do the same thing with source code stored on **GitHub**. Hadley Wickham has actually made the whole process easier by combining the `getURL`

, `textConnection`

, and `source`

commands into one function: `source_url`

. This is in his devtools package.

Imagine we have a .R source code file like this:

# Make cars scatter plot library(ggplot2) Plot <- qplot(cars$dist, cars$speed) + theme_bw() print(Plot)

It is hosted on **GitHub** with the URL: https://raw.github.com/christophergandrud/christophergandrud.github.com/master/SourceCode/CarsScatterExample.R

So to run this source code directly in **R** all we need to type is:

library(devtools) SourceURL <- "https://raw.github.com/christophergandrud/christophergandrud.github.com/master/SourceCode/CarsScatterExample.R" source_url(SourceURL)

There you go.

You can also directly source GitHub gists (which are nice for sharing short bits of code) with the `source_gist`

command.
