So OpenCPU is pretty awesome. You can run R in a browser using URL calls with an alphanumeric code (e.g., x3e50ee0780) defining a stored function, and any arguments you pass to it.

Go here to store a function. And you can output lots of different types of things: png, pdf, json, etc - see here.

Here’s a function I created:

It makes a ggplot2 graphic of your watchers and forks on each repo (up to 100 repos), sorted by descending number of forks/watchers.

Here’s an example from the function. Paste the following in to your browser and you should get the below figure.

And you can specify user or organization name using arguments in the URL
