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, read.socrata() returns an R data frame. Converts dates to POSIX format. Supports CSV and JSON download file formats from Socrata. Manages the throttling of data returned from Socrata and allows users to provide an application token. Supports SoDA query parameters in the URL string for further filtering, sorting, and queries.

Use ls.socrata() to list all datasets available on a Socrata webserver.

Example: Reading SoDA valid URLs

earthquakesDataFrame <- read.socrata("http://soda.demo.socrata.com/resource/4334-bgaj.csv")
nrow(earthquakesDataFrame) # 1007 (two "pages")
class(earthquakesDataFrame$Datetime[1]) # POSIXlt

Example: Reading "human-readable" URLs

earthquakesDataFrame <- read.socrata("https://soda.demo.socrata.com/dataset/USGS-Earthquakes-for-2012-11-01-API-School-Demo/4334-bgaj")
nrow(earthquakesDataFrame) # 1007 (two "pages")
class(earthquakesDataFrame$Datetime[1]) # POSIXlt

Example: Using API key to read datasets

token <- "ew2rEMuESuzWPqMkyPfOSGJgE"
earthquakesDataFrame <- read.socrata("http://soda.demo.socrata.com/resource/4334-bgaj.csv", app_token = token)
nrow(earthquakesDataFrame)

Example: List all datasets on portal

allSitesDataFrame <- ls.socrata("https://soda.demo.socrata.com")
nrow(allSitesDataFrame) # Number of datasets
allSitesDataFrame$title # Names of each dataset
