ggplot2 ------------------------------------------------------------

ggplot2 is a plotting system for R, based on the grammar of graphics, which tries to take the good parts of base and lattice graphics and avoid bad parts. It takes care of many of the fiddly details that make plotting a hassle (like drawing legends) as well as providing a powerful model of graphics that makes it easy to produce complex multi-layered graphics.

ggplot2 0.8 (2008-11-18)

The two biggest new features in this release are the (long awaited) ability to have scales that vary between facets, and a faceting system that works like lattice (facet_wrap). From qplot, you can use facet_wrap by specifying one sided formula (~ colour, as opposed to . ~ color). To see some potential uses for these new features, see the "Positioning" chapter of the book or the documentation for facet_wrap and facet_grid. Implementing these changes has required a rewrite of large parts of the coordinate systems code, so if anything seems strange with non-Cartesian coordinate systems, please get in touch.

I've also made another round of tweaks to make the plots more aesthetically pleasing. This includes using a bright blue colour for geoms used to add statistical summaries to plots (contour, smooth, and quantiles), and tweaking the default colour scheme for the continuous colour scale. Please let me know what you think. Remember that most of these options are controllable with the theming system - see the book chapter "Polishing your plots for publication".

Accompanying this new release of the package is an updated and expanded version of the book. The content of the book is now largely complete (~170 pages), and over the coming months I will be working on make it polished and easy to understand. See http://had.co.nz/ggplot2/book. I love to hear your feedback about the book, but at this point please don't bother reporting minor typos, I would much rather hear about what you want to do, but can't figure out from the book.
