depth.contours: Depth Contours

In ddalpha: Depth-Based Classification and Calculation of Data Depth

Depth Contours

Description

Builds the data depth contours for 2-dimensional data.

Usage

depth.contours(data, depth, 
              main = "", xlab="", ylab = "", 
              drawplot = T, frequency=100, levels = 10,
              col = "red",
              ...)

Arguments

data	2-dimensional numeric data frame or matrix
depth	the name of the depth function. The list of the supported depths and described in the topic depth..
main	an overall title for the plot: see title
xlab, ylab	labels of the axes
drawplot	if set to false, the contours are built on the existing plot.
frequency	number of points on each direction, x and y. Impacts the smoothness of the contours.
levels	numeric vector of levels at which to draw contour lines. If the vector contains only ONE element, the levels are generated automatically as seq(0, max(depth), length.out = levels).
col	color, used to draw points and contours
...	additional parameters passed to the depth functions and to plot
