Finding and formatting numerical data for analysis in R or Excel or indeed any application is a pain that all real world data analysts know all too well. In aggregate I have probably spent weeks of my life trying to find data on the web. And several more weeks validating, formatting and cleaning the data. Analysis offers data scientists interesting, intellectually stimulating problems. But data acquisition, the necessary precursor, offers only tedium and pain. It's a time vampire.
