R: Plot a tessellation

plot.tess {spatstat} | R Documentation

## Plot a tessellation

### Description

Plots a tessellation.

### Usage

      ## S3 method for class 'tess'
    plot(x, ..., main, add=FALSE,
                          show.all=!add, col=NULL, do.plot=TRUE,
                          do.labels=FALSE,
                          labels=tilenames(x), labelargs=list())

### Arguments

`x` | Tessellation (object of class `"tess"`) to be plotted.
`...` | Arguments controlling the appearance of the plot.
`main` | Heading for the plot. A character string.
`add` | Logical. Determines whether the tessellation plot is added to the existing plot.
`show.all` | Logical value indicating whether to plot everything including the main title and the observation window of `x`.
`col` | Colour of the tile boundaries. A character string. Ignored for pixel tessellations.
`do.plot` | Logical value indicating whether to actually perform the plot.
`do.labels` | Logical value indicating whether to show a text label for each tile of the tessellation.
`labels` | Character vector of labels for the tiles.
`labelargs` | List of arguments passed to `text.default` to control display of the text labels.

### Details

This is a method for the generic `plot` function for the class `"tess"` of tessellations (see `tess`).

The arguments `...` control the appearance of the plot. They are passed to `segments`, `plot.owin` or `plot.im`, depending on the type of tessellation.

### Value

(Invisible) window of class `"owin"` specifying a bounding box for the plot (including a colour ribbon if plotted).

### Examples

      A <- tess(xgrid=0:4,ygrid=0:4)
      plot(A, col="blue", lwd=2, lty=2)
      B <- A[c(1, 2, 5, 7, 9)]
      plot(B, hatch=TRUE)
      v <- as.im(function(x,y){factor(round(5 * (x^2 + y^2)))}, W=owin())
      levels(v) <- letters[seq(length(levels(v)))]
      E <- tess(image=v)
      plot(E)
