Looking for an overview of different #RStats packages for visualising spatial data? 📊 Here's a previous blog post of mine: nrennie.rbind.io/blog/r-packa... This blog post is almost three years old now, but all of the code still works! #DataViz #RSpatial #30DayMapChallenge

R packages for visualising spatial data – Nicola Rennie

Throughout the #30DayChartChallenge I made most of my maps with R. This blog post details the R packages I find myself using most often when visualising spatial data.
