With this short, hands-on tutorial, Data Mashups in R, you learn how to collect online data, massage it into a reasonable form, and work with it using R facilities to interact with web servers, parse HTML and XML, and more. Rather than use canned sample data, you'll plot & analyze current home foreclosure auctions in Philadelphia.This practical mashup exercise shows you how to access spatial data in several formats locally and over the Web to produce a map of home foreclosures. It's an excellent way to explore how the R environment works with R packages and performs statistical analysis.Data Mashups in R:- Parse messy data from public foreclosure auction postings;- Plot the data using R's PBS mapping package;- Import US Census data to add context to foreclosure data;- Use R's lattice and lattice Extra packages for data visualization;- Create multidimensional correlation graphs with the pairs() scatterplot matrix package.
