formatR update (0.1-5)

December 3, 2010

he formatR package has been silent for quite a few months now. Recently I’ve been moving my old packages from R-Forge to GitHub, and I finally killed several things on my TODO list. In the past, I made an awkward decision to let formatR depend on the animation package, which was ridiculous. Ronggui suggested me

Rd2roxygen: Convert Rd to roxygen documentation

December 1, 2010
By

must admit that I have been tired of maintaining my R packages for a long time, and the main reason is I feel really uncomfortable with writing R documentations (Rd). The required structure of an R package mainly includes two directories R and man — the former for the R source code (typically functions), and

Animate .gif images in R / ImageMagick

Yesterday I surfed the web looking for 3D wireframe examples to explain linear models in class. I stumbled across this site where animated 3D wireframe plots are outputted by SAS.  Below I did something similar in R. This post shows the few steps of how to create an animated .gif file using R and ImageMagick.

Because it’s Friday: Asteroids

November 12, 2010

A huge mass of rock hurtling in from space could really make a mess of your weekend plans. So it's comforting to know that the world's astronomers are out there keeping an eye for any potential earth-grazers. See their discoveries over the past 30 years in this beautifully-designed animation: Earth crossers are in red; earth approachers are in yellow;...

Animated plots in R and LaTeX

I like to use animated plots in my talks on functional time series, partly because it is the only way to really see what is going on with changes in the shapes of curves over time, and also because audiences love them! Here is how it is done. For LaTeX, you need to create every

October 12, 2010

In case you missed them, here are some articles from August of particular interest to R users. We presented a profile of Hadley Wickham, author of many popular R packages including ggplot2 and reshape. We riffed the design of the new Twitter website into a discussion on calculating the Golden Mean with R. Several readers contributed 1-liners based on...

Add an animated R plot to your LaTeX document

My first introduction with LaTeX was not very pleasant. I got tired and frustrated by writing so many codes for producing a simple document; but a few days ago I could write a function for producing an animated plot in R and also could export it to my LaTeX document with all its animations intact (using animation package of...

Add an animated R plot to your LaTeX document

It is possible to animate a R plot and this plot can also be exported to a LaTeX document with all its animations intact. Adding this animated plot to a PowerPoint slide or save it as a flash movie file (that you can upload to YouTube) is also possible. In this article I will try to show how these...

ICOADS

Just a short update on ICOADS. I started out an ICOADS project with grand plan to reprocess the observation files into a “raster” format. That ends up being a really big job. Along the way I had to learn a new package Rcurl and relearn some old Unix skills for compiling RCurl. Along the way

Mandelbrot Set, evolved

The Mandelbrot Set is perhaps the most famous fractal of all time. It's simple in its definition: iterate the complex equation zn+1 = zn2 + c (starting with z0 = 0) for various values of c, and if doesn't go to infinity then c is part of the Mandelbrot Set. The result, however, is amazingly complex. Thinking of c...
