ben

Personal R package of Ben Cunningham.

This repository is a compilation of functions that I find useful. It is inspired by Hilary Parker's article Personal R Packages. To get started creating your own packages, I recommend her tutorial.

This project is subject to change erratically, so it would be unwise to rely on anything here as a long-term dependency. Feel free to clone anything you find particularly valuable for use in your own personal function repo.

Installation

devtools::install_github("benjcunningham/ben")

Usage Tips

.RProfile

The following options should be set in .Rprofile to customize the default behaviour of some functions.

• ben.alarms: Directory of sound assets; for example ~/R/alarms/
• ben.alarmdefault: Default sound file to play; for example Hangouts.wav

Pushbullet

To take advantage of the Pushbullet notification wrappers, RPushbullet should be configured with ~/.rpushbullet.json or equivalent global options. In the past, it was necessary to attach RPushbullet to make API calls; this is no longer the case, but you must set options in the JSON dotfile.

Jekyll

To serve Jekyll blog posts that contain JavaScript frames (e.g. Leaflet), follow the following workflow:

• Write the post using R Markdown and save it in a non-served project directory like _R. Include only YAML front matter that pertains to rendering the document as HTML. For example, in the file _R/test-post.Rmd:

---
output:
  html_document:
    theme: null
    self_contained: true
---

Hello world!

• If using the default directories, make sure an _includes/htmlwidgets directory exists before proceeding. Render the post as HTML using:

ben::knit_htmlwidgets("./_R/test-post.Rmd")

• Create a placeholder R Markdown file in your regular post directory (usually _source). Include regular YAML front matter and a Jekyll liquid include to the rendered HTML post. For example, in the file _source/2016-01-01-test-post.Rmd:

---
layout: post
title: "Test Post"
date: "January 1, 2016"
---

{% include htmlwidgets/test-post.html %}

• Build the site with servr::jekyll().
