"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 none of the 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."

One of the great things about R is the inbuilt plotting and data exploration tools. Having this all in one spot is fantastic. However, when it comes to print ready graphics, the base graphics system can be a nightmare to get right. ggplot is a widely used alternative to base and lattice graphics, written by Hadley Wickham, that addresses many of the shortcomings of base and lattice.

In this meetup we will cover:

• A short introduction to graphics in R & how the grammar of graphics differs from base. (Josh Reich)
  
• GGPlot - Overview & tutorial (Harlan Harris)
  
• Graphics Q&A + Show & Tell. (Drew Conway)
