This based on 'counting' up and down based on the tile name.
tile_neighbors(nm, tileset, iterate = 0, diagonal = FALSE)
nm | Character string or factor: name of a tile, e.g., |
---|---|
tileset | Admissible tile names; if missing and |
iterate | internal - do not change default: to control behaviour in an interactive call to this function. |
diagonal | if |
Character string.
