Connected Components of Tiles of a Tessellation

Given a tessellation, find the topologically-connected pieces of each tile, and make a new tessellation using these pieces.

Usage
# S3 method for tess
connected(X, …)
Arguments
X

A tessellation (object of class "tess").

Arguments passed to as.mask to determine the pixel resolution.

Details

The function connected is generic. This function connected.tess is the method for tessellations.

Given the tessellation X, the algorithm considers each tile of the tessellation, and identifies its connected components (topologically-connected pieces) using connected.owin. Each of these pieces is treated as a distinct tile and a new tessellation is made from these pieces.

The result is another tessellation obtained by subdividing each tile of X into one or more new tiles.

Value

Another tessellation (object of class "tess").
