lawn_midpoint: Get a point midway between two points

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

Description

Takes two data-Point's and returns a point midway between them

Usage

lawn_midpoint(pt1, pt2, lint = FALSE)

Arguments

pt1	First data-Feature<(data-Point)>
pt2	Second data-Feature<(data-Point)>
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

Value

A data-Feature<(data-Point)> midway between pt1 and pt2
