mesh_distance: Distance between regional meshes
In japanmesh: Functions for the Japanese Regional Mesh Codes ('JIS X 0410')

If mesh and mesh_to are both vectors, the distance between mesh and mesh_to is calculated. If mesh is a list, The path distance of each element is calculated.

1	mesh_distance(mesh, mesh_to, close = FALSE, type = "keep_na")

`mesh`	A `mesh` vector or a list of `mesh` vector.
`mesh_to`	A `mesh` vector.
`close`	Should the path of each element be closed when `mesh` is a list?
`type`	How is the NA mesh treated when `mesh` is a list? `"skip_na"` skips the `NA` mesh and connects the paths. `"keep_na"` by default.
