clipHullsToLand: Clips convex hulls to landmasses

In JCur96/sfe: Adds Useful Tools for Ecologists to the sf Package

Description

clipHullsToLand returns the clipped convex hulls by species for a single object of class sf (a data frame).

Usage

clipHullsToLand(x)

Arguments

x	object of class sf, sfc or sfg

Details

These hulls are clipped to landmasses only. To generate hulls and clip them to landmasses with a single function see makeLandClippedHulls. x must have both a geometry and a binomial column present to work.

For more felxible convex hull generation see st_convex_hull

Landmasses used to clip to are generated from the rnaturalearth package using the ne_countries function. please see its documentation here ne_countries for a full breakdown.

Value

Returns object x with clipped convex hulls computed and stored in the convex_hull column.

Examples

data.frame <- clipHullsToLand(data.frame)
