A Better Way To Read Nest Data Into R

September 10, 2015 | hrbrmstr

I glimpsed a post in the RSS feeds today on how to connect Nest data with a Shiny dashboard and was compelled to post a less brute-force way to get data from the Nest API. The authors of the Shiny+Nest post used system calls to curl and regular expression ... [Read more...]

Roll Your Own Stats and Geoms in ggplot2 (Part 1: Splines!)

September 8, 2015 | hrbrmstr

A huge change is coming to ggplot2 and you can get a preview of it over at Hadley’s github repo. I’ve been keenly interested in this as I will be fixing, finishing & porting coord_proj to it once it’s done. Hadley & Winston have re-built the ggplot2 with ...

Three New #rstats Twitter Bots To Follow

September 6, 2015 | hrbrmstr

I engage with the Stack[Overflow|Exchange] community quite a bit and was super-happy @treycausey made the Stack Overflow #rstats bot (@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 ... [Read more...]

Coloring (and Drawing) Outside the Lines in ggplot

August 27, 2015 | hrbrmstr

Time for another Twitter-inspired blog post this week, this time from a tweet by @JonKalodimos: Is there a way to do this in #rstats #ggplot2 https://t.co/kxWQFlYpbB— Jonathan Kalodimos (@JonKalodimos) August 27, 2015 I had seen and appreciated Ann’s post on her makeover of the main graphic in NPR’...

New Pacakge “docxtractr” – Easily Extract Tables From Microsoft Word Docs

August 24, 2015 | hrbrmstr

This is more of a follow-up from yesterday’s post. The hack and function in said post was fine, but it was limited to uniform tables and made you do more work than you had to. So, there’s now a devtools-installable package on github that makes it way easier ...

Using R To Get Data Out Of Word Docs

August 23, 2015 | hrbrmstr

This was asked on twitter recently: Is it possible to import data entered in MS Word into R – I have multiple tables in 235 files that need importing #rstats— Richard Telford (@richardjtelford) August 23, 2015 The answer is a very cautious “yes”. Much depends on how well-formed and un-formatted the table is. Take ...

Doh! I Could Have Had Just Used V8!

August 21, 2015 | hrbrmstr

An R user recently had the need to split a “full, human name” into component parts to retrieve first & last names. The full names could be anything from something simple like “David Regan” to more complex & diverse such as “John Smith Jr.”, “Izaque Iuzuru Nagata” or “Christian Schmit de la ... [Read more...]

Track Hurricane Danny (Interactively) with R + leaflet

August 20, 2015 | hrbrmstr

Danny became the first hurricane of the 2015 Season, so it’s a good time to revisit how one might be able to track them with R. We’ll pull track data from Unisys and just look at Danny, but it should be easy to extrapolate from the code. For this ...

cdcfluview – On The Way to “CRAN 7K”

August 9, 2015 | hrbrmstr

I like to turn coincidence into convergence whenever possible. This weekend, a user of cdcfluview had a question that caused me to notice a difference in behaviour between the package was interacting with CDC FluView API, so I updated the package to accommodate the change and the user. Around the ... [Read more...]

Paste chrome://settings/searchEngines into your location bar and hit return/enter Scroll down until the input boxes show, enabling you to add a search engine For “Add ... [Read more...]

Speeding Up Your Quest(s) For “R Stuff”

August 5, 2015 | hrbrmstr

I use Google quite a bit when conjuring up R projects, whether it be in a lazy pursuit of a PDF vignette or to find a package or function to fit a niche need. Inevitably, I’ll do something like this (yeah, I’m still on a mapping kick) and ...

Achieve Charting Zen With TauCharts

August 4, 2015 | hrbrmstr

There was some chatter on the twitters this week about a relatively new D3-based charting library called TauCharts (also @taucharts). The API looked pretty clean and robust, so I started working on an htmlwidget for it and was quickly joined by the Widget Master himself, @timelyportfolio. TauCharts definitely has ...

Two New R Packages – qrencoder & passwordrandom

August 2, 2015 | hrbrmstr

Believe it or not, there are two [1] [2] questions on @StackOverflowR about how to make QR codes in R. I personally think QR codes are kinda hokey, but who am I to argue with pressing needs of the #rstats community? I found libqrencode and it’s highly brew-able and apt-able (probably ...

Introducing the nominatim geocoding package

July 29, 2015 | hrbrmstr

In the never-ending battle for truth, justice and publishing more R packages than Oliver, I whipped out an R package for the OpenStreetMap Nominatim API. It actually hits the MapQuest Nominatim Servers for most of the calls, but the functionality is the same. The R package lets you: address_lookup: ...

Making Static/Interactive Voronoi Map Layers In ggplot/leaflet

July 26, 2015 | hrbrmstr

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 ...

Roll Your Own Gist Comments Notifier in R

July 25, 2015 | hrbrmstr

As I was putting together the coord_proj ggplot2 extension I had posted a (https://gist.github.com/hrbrmstr/363e33f74e2972c93ca7) that I shared on Twitter. Said gist received a comment (several, in fact) and a bunch of us were painfully reminded of the fact that there ... [Read more...]

A Path Towards Easier Map Projection Machinations with ggplot2

July 24, 2015 | hrbrmstr

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 ...

Using the new ‘viridis’ colormap in R (thanks to Simon Garnier)

July 20, 2015 | hrbrmstr

Nathaniel Smith and Stéfan van der Walt presented [YouTube] a new colormap (for Python) at SciPy 2015 called viridis. From the authors: The default colourmap in Matplotlib is the colourful rainbow-map called Jet, which is deficient in many ways: small changes in the data sometimes produce large perceptual differences and ...

It’s not on CRAN yet, but there’s a devtools-installable R package for getting data from the OMDB API. It covers all of the public API endpoints: find_by_id: Retrieve OMDB info by IMDB ID search find_by_title: Retrieve OMDB info by title search get_actors: Get ...

Faceted “World Population by Income” Choropleths in ggplot

July 9, 2015 | hrbrmstr

Poynter did a nice interactive piece on world population by income (i.e. “How Many Live on How Much, and Where”). I’m always on the lookout for optimized shapefiles and clean data (I’m teaching a data science certificate program starting this Fall) and the speed of the site ...
