PL94171: Tabulate P.L. 94-171 Redistricting Data Summary Files

Lifecycle: experimental CRAN status R-CMD-check CRAN downloads

The PL94171 package contains tools to process legacy format summary redistricting data files produced by the United States Census Bureau pursuant to P.L. 94-171. These files are generally available earlier but are difficult to work with as-is.

Installation

Install the latest version from CRAN with:

install.packages("PL94171")

You can also install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("CoryMcCartan/PL94171")

Basic Usage

Just need block- or precinct-level data for total and voting-age population by race? Then pl_tidy_shp() is all you need.

library(PL94171)
# put the path to the PL 94-171 files here, or use `pl_url()` to download them
pl_path = system.file("extdata/ri2018_2020Style.pl", package="PL94171")
pl_tidy_shp("RI", pl_path)
