Species occurrence data

The rOpenSci projects aims to provide programmatic access to scientific data repositories on the web. A vast majority of the packages in our current suite retrieve some form of biodiversity or taxonomic data. Since several of these datasets have been georeferenced, it provides numerous opportunities for visualizing species distributions, building species distribution maps, and for using it analyses such...

Above Average: Analyzing Self-Rated Qualities in R

Numerous psychological studies have demonstrated that people often have an inflated perception of their personal qualities. From work performance to driving skills, people report being above average in relation to others when it comes to many arenas. This extends to how people perceive their own physical attractiveness and intelligence levels. This begs the important question: Are

PK calculations for infusion at constant rate

In this third PK posting I move to chapter 10, study problem 4 of Rowland and Tozer (Clinical pharmacokinetics and pharmacodynamics, 4th edition). In this problem one subject gets a 24 hours continuous dose. In many respects the Jags calculation is not very different from before, but the relation between parameters in the model and PK parameters is a...

Moving the North Pole to the Equator

I am still working with @3wen on visualizations of the North Pole. So far, it was not that difficult to generate maps, but we started to have problems with the ice region in the Arctic. More precisely, it was complicated to compute the area of this region (even if we can easily get a shapefile). Consider the globe, worldmap <- ggplot()...

Aggregation of point data to polygons MKII – US states

After a colleague of mine requested an illustration of the aggregation technique that was part of an introduction to spatial data in R, I decided to revisit aggregation. The first article I posted here on the subject used data from London; this one is slightly different, using Twitter data aggregated to the state level in the USA. All example code...

Bayesian Search Models

Bayesian Search Theory The US had a pretty big problem on their hands in 1966. Two planes had hit each other during a in-flight refueling and crashed. Normally, this would be an unfortunate thing and terrible for the families of those involved in the crash but otherwise fairly limited...

rnoaa – Access to NOAA National Climatic Data Center data

We recently pushed the first version of rnoaa to CRAN - version 0.1. NOAA has a lot of data, some of which is provided via the National Climatic Data Center, or NCDC. NOAA has provided access to NCDC climate data via a RESTful API - which is great because people like us can create clients for different programming...

Last year in my post d3 <- R with rCharts and slidify I predicted: I have a feeling that nearly every R user of lattice or ggplot2 will be familiar with Ramnath’s brilliance by the end of the year 2013. He might even convince some d3 users to try a little R. Now Ramnath has started a blog...

Slidify my R journey from @matlabulous to rCrimemap

My LondonR Talk Thanks to Mango Solutions (LondonR organiser), I was given the opportunity last night to talk about my mini project ‘CrimeMap’. Instead of going through all the technical details behind the scenes, I chose to talk the audience through my R journey from a noob to a heavy user. CrimeMap was used as a...
