You can query global climate data from the KNMI Climate Explorer (the KNMI is the Royal Netherlands Metereological Institute) with R.Here's a little example how I retreived data for my hometown Innsbruck, Austria and plotted annual total precipitation....
Hi internet, we’re happy to be here. We’ll be covering a range of topics in this blog — we’ll talk to inventors and creative people as they launch their projects from Kickstarter and IndieGoGo, we’ll talk about the crowd-funding industry and where it’s headed, and we’ll dig into the details of pricing and success rates … Continue reading...
In case you missed them, here are some articles from June of particular interest to R users. RStan is a new package for Bayesian modeling with R. It's faster and can fit more highly-correlated models than the MCMC sampler of BUGS and JAGS. Biostatistician Corey Chivers used R to animate the epidemic-like growth of retailer Walmart in the US....
This image comes from the cover of Preliminary Papers of the Second International Workshop on Artificial Intelligence and Statistics (1989). Someone abandoned it in the lobby of my building at school. Whatever for, I’ll never know. I just love the idea of machine learning/AI/Statistics evoking a robot hand drawing a best fit line through some 
Have you ever exported an R plot as a PDF and tried to edit it further by importing the PDF into a vector graphics program like Adobe Illustrator or Inkscape? What typically happens is the points on the plot get...
Mango Solutions host BaselR, a free, open and informal R user group for those using or interested in using R. There will be a few short R related presentations and an opportunity to meet and chat with other R users over a drink. Date: Thursday 13th September at 6.30pm. Venue : transBarent, Viaduktstrasse 3, Basel (by the train station)...
Consider a (stationary) autoregressive process, say of order 2, for some white noise with variance . Here is a code to generate such a process, > phi1=.5 > phi2=-.4 > sigma=1.5 > set.seed(1) > n=240 > WN=rnorm(n,sd=sigma) > ...
Update Oct-23: Added a new parameter add to the function. Now multiple groups can be plotted in a single plot (see example in my comment) As a follow-up on my R implementation of Solomon’s watercolor plots, I made some improvements to the function. I fine-tuned the graphical parameters (the median smoother line now diminishes faster
Suicide is a tragic and complex problem. This week New Zealand’s Chief Coroner released its annual statistics on suicide, which come with several tables and figures. One of those figures refers to monthly suicides in the Christchurch region (where I … Continue reading →
In an image each pixel is a color and that color hava a RGB representation, this means each color is represented by a triplet. For example the red in this representation is (250, 0, 0), black is (0,0,0) and white is (250, 250, 250) (see here more ...
