Data Mashups in R (Paperback)
Jeremy Leipzig, Xiao-Yi Li
Data analysis is more than means and standard deviations. This book is a case study of how you can push R into new territory to analyze online real-world data. The authors scrape public foreclosure records for Philadelphia, geocode them, plot them by neighborhood, and analyze the results, using R facilities to interact with web servers, parse HTML and XML, and more.
