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

[![Lifecycle:

experimental](https://img.shields.io/badge/lifecycle-stable-green.svg)](https://lifecycle.r-lib.org/articles/stages.html#stable)

[![CRAN status](https://www.r-pkg.org/badges/version/PL94171)](https://CRAN.R-project.org/package=PL94171)

![CRAN downloads](http://cranlogs.r-pkg.org/badges/grand-total/PL94171)

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:

``` r

install.packages("PL94171")

```

You can also install the development version from [GitHub](https://github.com/) with:

``` r

# 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.

```{r}

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)

```
