Plotting in R with ggplot2
ggplot2 is a powerful graphing package in R that can be used to create professional looking plot for reports, essays or papers. It can create a variety of plots including boxplots, scatterpots and histograms and they can be highly customised to suit your data.
The package is named after a book called The Grammar of Graphics about how to effectively communicate data graphically.
