Spatial polygons from an icosahedral grid — SpPolygons • icosa

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

Usage

SpPolygons(gridObj, ...)

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

# S4 method for 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)
