It’s an episode of firsts on the R-Podcast! In this episode recorded on location I had the honor and privilege of interviewing Yihui Xie, author of many innovative packages such as knitr and animation. Some of the topics we discussed include: Yihui’s motivation for creating knitr and some key new features How markdown plays a

R programming challenge: Escape the zombie horde
So when the world is taken over by a Zombie horde, you're going to want to figure out a way to get the human population to safety. This R script by econometrician Francis Smart won't help you do that exactly, but given a list of waypoints to navigate through zombie-infested lands to a safe house, it will tell you...
Strategic Zombie Simulation – Animation – Jimmy’s Down
# Escape Zombie Land!# This is a simulation an escape from a hot zombie zone. It freezes and gives an error if you get get killed so you had best not. To play it you attempt to navigate the zone by constructing waypoints.# Overall, it is no...
Animations Understood
When I first saw a graphic made from Yihui’s animation package (Xie, 2012) I was amazed at the magic and thought “I could never do that”. Passage of time… One night I found myself bored and as usual avoiding work. … Continue reading →
Spatial Critter Swarming Simulation
(This article was first published on Econometrics by Simulation, and kindly contributed to R-bloggers) # I am interested in how small bits of individualized instructions can create collective action.# In this simulation I will give a single instruction to each individual in the swarm.# Choose another individual who is not too close, then accelerate towards that individual.# I also...
Bubble sort implemented in pure R
Please note that this is programming I purely did for the learning experience. The pure R bubble sort implemented in this post is veeeeery slow for two reasons: Interpreted code with lots of iteration is very slow. Bubble sort is… See more ›
Animation, from R to LaTeX
Just a short post, to share some codes used to generate animated graphs, with R. Assume that we would like to illustrate the law of large number, and the convergence of the average value from binomial sample. We can generate samples using > n=200 > k=1000 > set.seed(1) > X=matrix(sample(0:1,size=n*k,replace=TRUE),n,k) Each row will be a trajectory of heads and...
Kalkalash! Pinpointing the Moments “The Simpsons” became less Cromulent
Whenever somebody mentions “The Simpsons” it always stirs up feelings of nostalgia in me. The characters, uproarious gags, zingy one-liners, and edgy animation all contributed towards making, arguably, the greatest TV ever. However, it’s easy to forget that as a TV show “The Simpsons” is still ongoing—in its twenty-fourth season no less. For me, and

big geo-data visualisations
Spotting international conflict is very easy with the GDELT data set, combined with ggplot and R. The simple gif above shows snapshots of Russian/Soviet activity from January 1980 and January 2000. I think it also illustrates how Russia nowadays looks more to the east and the South than during the Cold War. The trend, though...
