GGally: Extension to ggplot2

ggplot2 is a plotting system for R based on the grammar of graphics. GGally extends ggplot2 by adding several functions to reduce the complexity of combining geoms with transformed data. Some of these functions include a pairwise plot matrix, a scatterplot plot matrix, a parallel coordinates plot, a survival plot, and several functions to plot networks.
