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.

Data Requirements:

London Sport Participation Shapefile. Download (requires unzipping)

poly_coords function. Download

Install the following packages (if you haven’t already done so):

maptools, RColorBrewer, ggplot2
