salem_region: Simple Features data for Salem

In salem: Provides Access to Salem Witchcraft Data

Description

A dataset containing map information for the three counties represented in the accused_witches data set (not including present-day Maine locations) in simple features format. It also includes associated data on accusations. This data should never be used to analyze accusations. The data is based on modern town boundaries from the Massachuessetts Document Repository. Some simple cleaning has been done to facilitate basic mapping. Specifically, the names Salem Town and Salem Village are used rather than the modern Salem and Danvers. Additionally, a field, TOWN_LABEL is attached to the largest area for each town or community.
