For those starting out with spatial data in R, Robin Lo

Tim Hortons Density Inspired by this post, I wanted to examine the locations and density of Tim Hortons restaurants in Canada. Using Stats Canada data, each census tract is queried on Foursquare for Tims locations. Setup options(stringsAsFactors = F) require(timmysDensity) require(plyr) require(maps) require(ggplot2) require(geosphere) Statistics Canada Census Data The actual Statistics Canada data at the dissemination block level can be downloaded from here.

This course is about getting to grips with the basics of the R command line for basic data analysis and visualisation. There's a focus on maps and ggplot2. The first part of the course uses Rich Harris's "Short Introduction to R" (here). The second part works through an "Introduction to Spatial Data and ggplot2" (Cheshire and Lovelace, 2013), which can be found...

This meant that for 24 days, every day, there was an interesting post featuring analysis and some excellent visualizations in R. I think it's an interesting (if very challenging) exercise and I'm going to try to do it myself this year.

The “IV Jornadas de usuarios de R” were held in Barcelona on November 15th and 16th of 2012. From the Barcelona’s Users Group (RugBcn) we want to highlight two workshops given by some of the RugBcn’s organizers : Ggplot2 and ggmaps by Lluís Ramon, Andreu Valls and Roger Borràs (in spanish).

UPDATE: A Shiny (dynamic) version of this is now available. We had yet-another power outage this morning due to the weird weather patterns of the week and it was the final catalyst I needed to crank out some R code to map the affected counties. Central Maine Power provides an outage portal where folks can
