The software underlying Reproducible Research with R and RStudio is constantly changing. This page contains a list of major software updates. I am continually working on an updated version of the Book that will include these updates.

## RStudio

Note that the book was written with the current development version of RStudio (version 0.98). It has not been officially released yet, but it can be freely downloaded for a variety of operating systems here. I've been using it for months now and it is generally very stable for all of the functions covered in the Book.

## knitr

Update to Chapter 8 (08-2013): From at least version 1.4.1 the R knitr package is now capable of highlighting syntax from a variety of non-R languages. To make this work properly you will need to install Andre Simon's highlight utility. See his website for download and installation instructions.

Update to Chapter 10 (08-2013):Current versions of knitr allow you to use the fig.align code chunk option with R Markdown documents to align an output figure in a document.
