lawn_buffer: Buffer a feature

Description

Calculates a buffer for input features for a given radius

Usage

lawn_buffer(input, dist, units = "kilometers", lint = FALSE)

Arguments

input

A Feature or FeatureCollection

dist

distance used to buffer the input

units

(character) Can be miles, feet, kilometers (default), meters, or degrees

lint

(logical) Lint or not. Uses geojsonhint. Takes up increasing time as the object to get linted increases in size, so probably use by default for small objects, but not for large if you know they are good geojson objects. Default: FALSE
