Plotting multivariate data using ggplot
The ggplot2 library has a host of plotting tools for multivariate data. You will use the ggpairs() function to produce richer plots similar to the pairs() plot. This plot can be adapted to provide different information in the upper and lower triangles and diagonal entries of the matrix of plots. By default, it provides the scatter plots in the lower triangle, densities in the diagonal entries, and correlation in the upper triangle of the matrix of plots.
