Arguments passed to the <code><a rd-options="sp:panel" href="/link/sp.lines?package=icosa&version=0.10.1&to=sp%3Apanel" data-mini-rdoc="sp:panel::sp.lines">sp.lines</a></code> method.

This function will invoke the <code>sp.lines</code> method of the <code><a href="/link/SpatialPolygons?package=icosa&version=0.10.1" data-mini-rdoc="icosa::SpatialPolygons">SpatialPolygons</a></code> class.

Employs triangular tessellation to refine icosahedra
defined in 3d space. The procedures can be set to provide a grid with a
custom resolution. Both the primary triangular and their inverted penta-
hexagonal grids are available for implementation. Additional functions
are provided to position points (latitude-longitude data) on the grids,
to allow 2D and 3D plotting, use raster data and shapefiles.
