The goal of legiscanrr is to provide tools in R to easily interact with the LegiScan API. You can use the API to retrieve information about legislations in US states and Congress, such as bill details, sponsors, full bill texts, roll call records and more.
This package contains two main groups of functions:
- Wrapper functions for LegiScan APi operations to retrieve
information from LegiScan API.
- API key from LegiScan is required. Register for a key here
- Data processing functions to parse information such as bill
metadata, bill sponsor, roll call votes, from the JSON files
retrieved via API or direct
download
- See documentation page for more details on the types of information we can extract.
For full reference of the package, see https://fanghuiz.github.io/legiscanrr/
You can install the development version from GitHub with:
