Download Aquamacs from and install it.Ģ) Now any file with an “.R” extension that is opened with aquamacs will automatically have syntax highlighting AND will allow you to start 64-bit R. No need to separately download ESS (emacs speaks statistics) or mess with the. You have a finite amount of keystrokes in your life.1) Aquamacs is terrific because it comes bundled with about everything you need to start using R with it.

Automating repetitive steps is one of the great benefits of knowing a bit about coding, even if the code is just a simple shell script. That’s why I set up an example project on Github using a Makefile and sample article (inspired by Rob Hyndman).

This post explains the structure of that project and explains how to modify it for your own purposes. a graphics library for storing plots and figures to include in your article.Ī drafts directory for LaTeX, including a generic starter article.a data directory for storing files (csv, rda, etc).a setup.R file for clearing the workspace, setting paths, and loading libraries.Running the Makefile with the example article in an otherwise-empty project directory will create: Using latex on aquamacs how to# It also supplies some starter code for the setup.R file in the main directory and a start.R file in the rcode directory. This takes the current user and sets relative paths to the project directories with simple variable references in R.

For example, after running setup.R in your analysis file you can switch to the data directory with setwd(pathData), then create a plot and save it after running setwd(pathGraphics). Because of the way the setup.R file works, you could have multiple users working on the same project and not need to change any of the other scripts. If you want to change this structure, there are two main ways to do it. You can add more (or fewer) directories by modifying the mkdir lines in the Makefile. You can add (or remove) text in the R files by changing the echo lines. If you decide to make major customizations to this file or already have your own structure for projects like this, leave a link in the comments for other readers. H/T to Josh Cutler for encouraging me to write a post about my project structure and automation efforts. As a final note, this is the second New Year’s Eve in a row that I have posted a tech tip. Update: If you’re interested in your own automated project setup, check out ProjectTemplate by John Myles White. Thank to Trey Causey on Twitter and Zachary Jones in the comments for sharing this. Say you have a file with many repeated, unnecessary lines that you want to remove. For safety’s sake, you would rather make an abbreviated copy of the file rather than replace it. You just iterate over the file, putting all lines the computer has already “seen” into a dictionary. Output = File.open(filename+'2.tex', 'w') tex files in mind, but easily adaptable: puts 'Filename?' If a line is not in the dictionary, it must be new, so write it to the output file. Where would this come in handy? Well, the. tex extension probably already gave you a clue that I am reducing redundancy in a file. In particular, I have an R plot generated as a tikz graphic. The R plot includes a rug at the bottom (tick marks indicating data observations)–but the data set includes over 9,000 observations, so many of the lines are drawn right on top of each other. To if (seen) & !(line.include? 'node') & !(line.include? 'scope') & !(line.include? 'path') & !(line.include? 'define') One special tweak for using the script above to modify tikz graphics files is to change the line if (seen) The compiler got peeved at having to draw so many lines, so Ruby helped it out by eliminating the redundancy.

Par(mfrow=c(1,2)) in R) so that Ruby won’t ignore seemingly redundant lines that are actually specifying new panes.
