SpPolygons: Spatial polygons from an icosahedral grid

In adamkocsis/icosa: Global Triangular and Penta-Hexagonal Grids Based on Tessellated Icosahedra

Spatial polygons from an icosahedral grid

Description

The function will create a SpatialPolygons class 2d representation of the icosahedral grid.

Usage

SpPolygons(gridObj, ...)

## S4 method for signature 'trigrid'
SpPolygons(gridObj, res = NULL)

## S4 method for signature 'hexagrid'
SpPolygons(gridObj, res = NULL)

Arguments

gridObj	(trigrid or hexagrid) An icosahedral grid.
...	Arguments passed to class-specific methods.
res	(numeric) The number of points inserted between two vertices, or NULL, if this is to be set by the package. The default method increases resolution with lower tessellation values, and is higher for higher absolute latitudes.

Value

A SpatialPolygons class object.

Examples

a <- trigrid()
sp <- SpPolygons(a)
