Maps with ggplot2
The ggplot2 package offers powerful tools to plot data in R. The plots are designed to comply with the “grammar of graphics” philosophy and can be produced to a publishable level relatively easily. For users wishing to create a good map without too much thought I would recommend this worksheet. For those without their own shapefiles who rely on the “maps” package they may wish to consult Hadley Wickham‘s ggplot2 book.
