Ggplot2

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 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. Documentation ggplot2 documentation is now available at docs.ggplot2.org. Mailing list You are welcome to ask ggplot2 questions on R-help, but if you’d like to participate in a more focussed mailing list, please sign up for the ggplot2 mailing list:

FAQ: Using a plugin to connect to a database How do I connect to a database by using a Stata plugin? ODBC vs. plugin The easiest way to import data from a database directly into Stata is to use the odbc command. However, there are occasions where the odbc command will not work or is not the best solution for importing data. Visualizing Facebook Friends With D3.js or “How Wolfram A while ago, Wolfram|Alpha got the ability to generate personal analytics based on your Facebook profile. It made some cool numbers and stuff, but the friend network graph was the most impressive: Wolfram|Alpha neatly separates your various social circles into clusters, based on proximity — with freaky accuracy. With the awesome D3.js library, along with some gratuitous abuse of the Facebook API, we can make our own!

Plot matrix with the R package GGally I am glad to have found the R package GGally. GGally is a convenient package built upon ggplot2 that contains templates for different plots to be combined into a plot matrix through the function ggpairs. It is a nice alternative to the more limited pairs function. The package has also functions to deal with parallel coordinate and network plots, none of which I have tried yet. The following code shows how easy it is to create very informative plots like the one in Figure 1. Mondrian (software) Mondrian is a general-purpose statistical data-visualization system. It features outstanding visualization techniques for data of almost any kind, and has its particular strength compared to other tools when working with Categorical Data, Geographical Data and LARGE Data. All plots in Mondrian are fully linked, and offer various interactions and queries. Any case selected in a plot in Mondrian is highlighted in all other plots.
