lawn: Client for 'Turfjs' for 'Geospatial' Analysis

Client for 'Turfjs' (<http://turfjs.org>) for 'geospatial' analysis. The package revolves around using 'GeoJSON' data. Functions are included for creating 'GeoJSON' data objects, measuring aspects of 'GeoJSON', and combining, transforming, and creating random 'GeoJSON' data objects.

Install the latest version of this package by entering the following in R:
install.packages("lawn")
