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, house = "upper", cb = FALSE,
  detailed = TRUE, ...)

Arguments

state

The two-digit FIPS code (string) of the state. Can also be state name or abbreviation (case-insensitive)

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).

detailed

(deprecated) Setting detailed to FALSE returns a 1:500k cartographic boundary file. This parameter will be removed in a future release.

...

arguments to be passed to the underlying `load_tiger` function, which is not exported. Options include refresh, which specifies whether or not to re-download shapefiles (defaults to FALSE), and year, the year for w
