Zellingenach: A visual exploration of the spatial patterns in the endings of German town and village names in R

Moritz Stefaner started off 2016 with a [very spiffy post](http://truth-and-beauty.net/experiments/ach-ingen-zell/) on _”a visual exploration of the spatial patterns in the endings of German town and village names”_. Moritz was [exploring some new data processing & visualization tools](https://github.com/moritzstefaner/ach-ingen-zell) for the post, but when I saw what he was doing I wondered how hard it would be… Continue reading →

Replicating NatGeo’s “Proper” Earthquake Map in R

I saw this post over at NatGeo over the weekend and felt compelled to replicate this: with ggplot2. Three shapefiles later and we have it close enough to toss into a post (and I really don’t believe the continent names are necessary). library(rgdal) library(ggplot2) library(ggthemes) library(ggalt) # devtools::install_github(“hrbrmstr/ggalt”) # grab these from http://rud.is/dl/quakefiles.tgz world <-… Continue reading →

A Package Full o’ Pirates & Makin’ Interactive Pirate Maps in arrrrrRstats

Avast, me hearties! It’s time four t’ annual International Talk Like a Pirate Day #rstats post! (OK, I won’t make you suffer continuous pirate-speak for the entire post) I tried to be a bit more practical this year and have two treasuRe chests for you to (hopefully) enjoy. A Package Full o’ Pirates I’ve covered… Continue reading →

Three New #rstats Twitter Bots To Follow

I engage with the Stack[Overflow|Exchange] community quite a bit and was super-happy @treycausey made the [Stack Overflow #rstats bot](https://twitter.com/StackOverflowR) (@StackOverflowR) since I’m also on Twitter alot (mostly hanging out in #rstats these days). However, #rstats questions exist in other Stack watering holes, like the [Geographic Information Systems Stack Exchange](http://gis.stackexchange.com/questions/tagged/r). [Cross Validated](http://stats.stackexchange.com/questions/tagged/r) and the fledgling [Data… Continue reading →

Introducing the nominatim geocoding package

In the never-ending battle for truth, justice and publishing more R packages than [Oliver](http://twitter.com/quominus), I whipped out an R package for the [OpenStreetMap Nominatim API](http://wiki.openstreetmap.org/wiki/Nominatim). It actually hits the [MapQuest Nominatim Servers](http://open.mapquestapi.com/nominatim/) for most of the calls, but the functionality is the same. The R package lets you: – `address_lookup`: Lookup the address of one… Continue reading →

Making Static/Interactive Voronoi Map Layers In ggplot/leaflet

Despite having shown various ways to overcome D3 cartographic envy, there are always more examples that can cause the green monster to rear it’s ugly head. Take the Voronoi Arc Map example. For those in need of a primer, a Voronoi tesslation/diagram is: …a partitioning of a plane into regions based on distance to points… Continue reading →

A Path Towards Easier Map Projection Machinations with ggplot2

The $DAYJOB doesn’t afford much opportunity to work with cartographic datasets, but I really like maps and tinker with shapefiles and geo-data when I can, plus answer a ton of geo-questions on StackOverflow. R makes it easy—one might even say too easy—to work with maps. All it takes to make a map of the continental… Continue reading →
