Plot a voronoi object

Plots the mosaic "x". Dashed lines are used for outer tiles of the mosaic.

# S3 method for class 'voronoi'
plot(x,add=FALSE,
                           xlim=c(min(x$tri$x)-
                             0.1*diff(range(x$tri$x)),
                             max(x$tri$x)+
                             0.1*diff(range(x$tri$x))),
                           ylim=c(min(x$tri$y)-
                             0.1*diff(range(x$tri$y)),
                             max(x$tri$y)+
                             0.1*diff(range(x$tri$y))),
                           all=FALSE,
                           do.points=TRUE,
                           main="Voronoi mosaic",
                           sub=deparse(substitute(x)),
                           isometric=TRUE,
                           ...)
