I just did this for what will hopefully be a book chapter on our Divided Education – Divided Citizens research project with NEPC. Explanation further below for anyone more interested in the actual topic About the graphic: I like raw-data plots like this, made possible by Hadley Wickhams’s amazing ggplot2 package for the stats package R. Eve...

Red dots are parents who know their parent representatives well, blue dots are parents who do not; i.e. colour is mapped to the variable par.rep...

Horizon plots with ggplot2, sort-of
The Timely Portfolio blog via R-bloggers has recently published some interesting entries about the value of horizon plots for visual comparison of a number of time series. Very nice it looks too.

Heatmap tables with ggplot2
I wrote before about heatmap tables as a better way of producing frequency or other tables, with a solution which works nicely in latex. It is possible to do them much more easily in ggplot2, like this library(Hmisc) library(ggplot2) library(reshape) data(HairEyeColor) P=t(HairEyeColor[,,2]) Pm=melt(P) ggfluctuation(Pm,type="heatmap")+geom_text...
