There are quite some nice possibilities to analyse spatial data in R and in the context of my current project I would like to use R more frequently to do that.
Until now I plot my maps with ggplot2 package that brings a lot of practical tools to plot and explore data. Still my maps are not nearly as good looking as the ones I used to plot in ArcGIS.
So for publishing purposes I wonder if there are any good tutorials, books, practical tips, packages etc. that I could use to experiment a little bit and make my maps more good looking?
