Computes the area of each tile in a tessellation.
tile.areas(x)
A tessellation (object of class "tess"
).
A numeric vector.
A tessellation is a collection of disjoint spatial regions
(called tiles) that fit together to form a larger spatial
region. See tess
.
This command computes the area of each of the tiles
that make up the tessellation x
.
The result is a numeric vector
in the same order as the tiles would be listed by tiles(x)
.
