hexify_quad_ij_to_cell: Convert Quad IJ coordinates to cell ID

In hexify: Equal-Area Hex Grids on the 'Snyder' 'ISEA' 'Icosahedron'

Convert Quad IJ coordinates to cell ID

Description

Converts Quad IJ coordinates to a global cell identifier. This is the final step in the coordinate pipeline.

Usage

hexify_quad_ij_to_cell(quad, i, j, resolution, aperture = 3L)

Arguments

quad	Quad number (0-11), integer or vector
i	Cell index along first axis, integer or vector
j	Cell index along second axis, integer or vector
resolution	Grid resolution level (0-30)
aperture	Grid aperture: 3, 4, or 7

Value

Numeric vector of cell IDs
