# connected.tess

##### 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"`

).

##### Examples

```
# NOT RUN {
BB <- grow.rectangle(Frame(letterR), 0.2)
H <- tess(tiles=list(IN=letterR, OUT=complement.owin(letterR, BB)))
opa <- par(mfrow=c(1,2))
plot(H, do.col=TRUE)
plot(connected(H), do.col=TRUE, col=2:4)
par(opa)
# }
```
