Randy George, an expert in web map applications, has been fascinated with computer graphics (especially maps) since the early ’80s. For much of that time, he says , the technology for mapping has been pretty static:
But now, with the advent of the R language , things have changed. "R changes things in the geospatial world", says Randy, and R has "evolved into a useful platform for ad hoc spatial analysis". In his blog post, "The R Project for Maps", he gives several examples of using R for creating maps, including this one of using the leaflet package to create an interactive map of census data:
Randy also gives several other examples of interactive R graphics behond maps, including this weather chart with an interactive slider based on the dygraphs package :
I’ve only included static screenshots of the various maps and charts above, so be sure to follow the link to Randy’s post linked below for the interactive versions with the R code used to create them.
