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...

Less wordy R

The Swarm Lab presents a nice comparison of R and Python code for a simple (read ‘one could do it in Excel’) problem. The example works, but I was surprised by how wordy the R code was and decided to check if one could easily produce a shorter version. The beginning is pretty much the

Package rinat use case: map of iNaturalist project

iNaturalist projects are collection of records posted on iNatualist. Now that we have a R package rinat from rOpenSci I thought of playing around with the data. Here is a function I wrote, to quickly map all the records of a project using ggmap package. We can used get_inat_obs_project function from rinat package to get
