Usage
# S3 method for tess
plot(x, ..., main, add=FALSE,

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

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