plot.tess: Plot a tessellation

Description

Plots a tessellation.

Usage

"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.

Value

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

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.

Examples

Run this code
  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)
