R Markdown

R Markdown is an authoring format that enables easy creation of dynamic documents, presentations, and reports from R. It combines the core syntax of markdown (an easy-to-write plain text format) with embedded R code chunks that are run so their output can be included in the final document. R Markdown documents are fully reproducible (they can be automatically regenerated whenever underlying R code or data changes).

magrittr: magrittr – a forward-pipe operator for R

Provides a mechanism for chaining commands with a new forward-pipe operator. Ceci n’est pas un pipe.

This is a post from the most understated package definition of the year department. magrittr is, much like every Scheme library ever, deceptively simple in its power and ease of use that it provides.
The README, API documentation, and vignette are really, really great, too. Be sure to grok the order-of-evaluation when you’ve got normal functions on the right-hand-side.

The Wealth of Information

A wealth of information creates a poverty of attention.

Force unified coding style from all your contributors

EditorConfig helps developers define and maintain consistent coding styles between different editors and IDEs. The EditorConfig project consists of a file format for defining coding styles and a collection of text editor plugins that enable editors to read the file format and adhere to defined styles. EditorConfig files are easily readable and they work nicely with version control systems.

littler: a scripting front-end for GNU R

littler provides the r program, a simplified command-line interface for GNU R. This allows direct execution of commands, use in piping where the output of one program supplies the input of the next, as well as adding the ability for writing hash-bang scripts, i.e. creating executable files starting with, say, #!/usr/bin/r.

Wonderful, wonderful to know that this exists as it fills a definite void.
