hexify_grid_to_cell: Convert longitude/latitude to cell ID using a grid object

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

Convert longitude/latitude to cell ID using a grid object

Description

Grid-based wrapper for hexify_lonlat_to_cell. Converts geographic coordinates to DGGRID-compatible cell IDs using the resolution and aperture from a grid object.

Usage

hexify_grid_to_cell(grid, lon, lat)

Arguments

grid	Grid specification from hexify_grid()
lon	Numeric vector of longitudes in degrees
lat	Numeric vector of latitudes in degrees

Value

Numeric vector of cell IDs (1-based)

See Also

lonlat_to_cell for the recommended S4 interface, hexify_grid_cell_to_lonlat for the inverse operation
