## S3 method for class 'tess': plot(x, ..., main, add=FALSE, col=NULL)
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. |
