R: Connected Components of Tiles of a Tessellation

connected.tess {spatstat} | R Documentation

## Connected Components of Tiles of a Tessellation

### Description

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

### Usage

    ## S3 method for class '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

      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)
