There are packages for this now!

2017-08-03: Since I wrote this in 2014, the universe, specifically Kirill Müller (https://github.com/krlmlr), has provided better solutions to this problem. I now recommend that you use one of these two packages:

rprojroot: This is the main package with functions to help you express paths in a way that will "just work" when developing interactively in an RStudio Project and when you render your file.
here: A lightweight wrapper around rprojroot that anticipates the most likely scenario: you want to write paths relative to the top-level directory, defined as an RStudio project or Git repo. TRY THIS FIRST.

I love these packages so much I wrote an ode to here.

I use these packages now instead of what I describe below. I'll leave this gist up for historical interest. 😆

For this tutorial, we have the following brief. That is: to take a file that contains many millions of lines of text, each one of them a single column — something that looks like this:

POPLKLMNE
GKITLOPOM
QASSLKOPI
== snip ==

...into multiple text files, each with a fixed number of lines in them, each with — instead of one column per line — several columns, separated with a comma. In other words, something that looks like this:

POPLKLMNE,GKITLOPOM,QASSLKOPI

	An implementation of the Bjorklund algorithm in JavaScript

	Inspired by the paper 'The Euclidean Algorithm Generates Traditional Musical Rhythms'
	by Godfried Toussaint

	This is a port of the original algorithm by E. Bjorklund which I
	found in the paper 'The Theory of Rep-Rate Pattern Generation in the SNS Timing Systems' by
	E. Bjorklund.
