state_legislative_districts: Download a state legislative districts shapefile into R - upper or lower

Description

This function allows you to download boundaries for state legislatures into R. Generally, state legislatures are comprised of an "upper" house, which is typically referred to as the Senate, and a "lower" house, which is often (but not exclusively) referred to as the House. The exception is Nebraska, which has a unicameral state legislature.

Usage

state_legislative_districts(
  state = NULL,
  house = "upper",
  cb = FALSE,
  year = NULL,
  ...
)

Arguments

state

The two-digit FIPS code (string) of the state. Can also be state name or abbreviation (case-insensitive). When NULL and combined with cb = TRUE, a national dataset of state legislative districts will be returned.

house

Specify here whether you want boundaries for the upper or lower house. Defaults to upper.

cb

If cb is set to TRUE, download a generalized (1:500k) cartographic boundary file. Defaults to FALSE (the most detailed TIGER/Line file).

year

the data year (defaults to 2020).

...

arguments to be passed to the underlying `load_tiger` function, which is not exported. Options include class, which can be set to "sf" (the default) or "sp" to request sf or sp class objects, and refresh, which specifies whether or not to re-download shapefiles (defaults to FALSE).
