RSocrata

A tool for downloading Socrata datasets as R data frames

Provided with a URL to a dataset resource published on a Socrata webserver, or a Socrata SoDA (Socrata Open Data Application Program Interface) web API query, or a Socrata "human-friendly" URL, returns an R data frame. Converts dates to POSIX format. Supports CSV download file formats from Socrata. Manages the throttling of data returned from Socrata. RUnit test coverage.
