depthContour: Approximate depth contours

In DepthProc: Statistical Depth Functions for Multivariate Analysis

Description

Draws an approximate contours of depth for bivariate data.

Usage

depthContour(x, xlim = extendrange(x[, 1], f = 0.1), ylim = extendrange(x[,
  2], f = 0.1), n = 50, pmean = TRUE, mcol = "blue", pdmedian = TRUE,
  mecol = "brown", legend = TRUE, points = FALSE, colors = heat_hcl,
  levels = 10, ...)

Arguments

x	Bivariate data
xlim	Determines the width of x-axis.
ylim	Determines the width of y-axis.
n	Number of points in each coordinate direction to be used in contour plot.
pmean	Logical. If TRUE mean will be marked.
mcol	Determines the color of lines describing the mean.
pdmedian	Logical. If TRUE depth median will be marked.
mecol	Determines the color of lines describing the depth median.
legend	Logical. If TRUE legend for mean and depth median will be drawn.
points	Logical. If TRUE points from matrix x will be drawn.
colors	function for colors pallete (e.g. gray.colors).
levels	number of levels for color scale.
...	Any additional parameters for function depth (such as method) or graphical parameters (e.g. lwd, lty, main).

Details

The set of all points that have depth at least α is called α - trimmed region. The α - trimmed region w.r.t. F is denoted by {D}_{α }(F) , i.e.,

{D}_{α }(F)=≤ft\{ z\in {{{R}}^{d}}:D(z,F)≥ α \right\}
