h3_line: Get Line Between Hexagons

In JohnCoene/h3inr: Hexagon-based Geographic Grid System

Description

Given two H3 indexes, return the line of indexes between them (inclusive).

Usage

h3_line(origin, destination)

Arguments

origin, destination

H3indices to draw line.

Details

This function may fail to find the line between two indexes, for example if they are very far apart. It may also fail when finding distances for indexes on opposite sides of a pentagon.

Value

A list of h3indices drawing line.

Note

Lines are drawn in grid space, and may not correspond exactly to either Cartesian lines or great arcs.

Examples

## Not run: 
hexagons <- geo_to_h3(quakes, lat, long)
