An R package for the OpenSecrets.org web services API.

OpenWeatherMap (OWM) <http://openweathermap.org/api> is a service providing weather related data.
           This package can be used to access current weather data for one location or several locations.
           It can also be used to forecast weather for 5 days with data for every 3 hours.

Provides string arithmetic, reassignment operators, logical operators
  that handle missing values, and extra logical operators such as floating point
  equality and all or nothing. The intent is to allow R users to write code that
  is easier to read, write, and maintain while providing a friendlier experience
  to new R users from other language backgrounds (such as 'Python') who are used
  to concepts such as x += 1 and 'foo' + 'bar'.
  Includes operators for not in, easy floating point comparisons, === equivalent, and SQL-like 
  like operations (), etc. 
  We also added in some extra helper functions, such as OS checks, pasting
  in Oxford comma format, and functions to get the first, last, nth, or most common 
  element of a vector or word in a string.

Reproducible, programmatic retrieval of datasets from the
    Roper Center data archive.  The Roper Center for Public Opinion
    Research <https://ropercenter.cornell.edu> maintains the largest 
    archive of public opinion data in existence, but researchers using
    these datasets are caught in a bind.  The Center's terms and conditions
    bar redistribution of downloaded datasets, but to ensure that one's 
    work can be reproduced, assessed, and built upon by others, one must
    provide access to the raw data one employed.  The `ropercenter`
    package cuts this knot by providing registered users with programmatic,
    reproducible access to Roper Center datasets from within R.
