Speeding up R computations Pt III: parallelization

January 8, 2013

In two previous posts, I have written about how you can speed up your R computations either by using strange notation and non-standard functions or by compiling your code. Last year my department bought a 64-core computational server, which allowed me ...

Speeding up R computations Pt II: compiling

April 27, 2012

A year ago I wrote a post on speeding up R computations. Some of the tips that I mentioned then have since been made redundant by a single package: compiler. Forget about worrying about curly brackets and whether to write 3*3 or 3^2 - compile...

The past few days I've been going through some R code that I wrote last year, when I was preparing a massive simulation-based power study for some tests for multivariate normality that I've been working on. My goal was to reduc...
