.plot.deldir.datautils:

Description

overrides the original plot.deldir function, to support background colors when printing the tesselation.

Usage

# S3 method for deldir
plot(x, add = FALSE, wlines = c("both", "triang", "tess"), 
    wpoints = c("both", "real", "dummy", "none"), number = FALSE, 
    cex = 1, nex = 1, col = NULL, lty = NULL, pch = NULL, xlim = NULL, 
    ylim = NULL, xlab = "x", ylab = "y", showrect = FALSE, fill = NULL, ...)
