Description

Computes data depth values for a bi-variate mesh of points w.r.t. a multivariate data set.

Arguments

data

Matrix of data where each row contains a d-variate point, w.r.t. which the depth is to be calculated.

notion

'aprojection' for asymmetric projection depth;
'betaSkeleton' for beta-skeleton depth (including lens and spherical depth);
'cexpchull' for continuous expected convex hull depth;
'cexpchullstar' for continuous modified expected convex hull depth;
'geometrical' for geometrical depth;
'halfspace' for the halfspace depth;
'L2' for L2-depth;
'mahalanobis' for Mahalanobis depth;
'projection' for projection depth;
'qhpeeling' for convex hull peeling (or onion) depth;
'simplicial' for simplicial depth;
'simplicialVolume' for simplicial volume (or Oja) depth;
'spatial' for spatial depth;
'zonoid' for zonoid depth.

freq

Frequency in abscisse and ordinate.

xlim

Range of values for abscisse.

ylim

Range of values for ordinate.

mah_estimate, …

Depth-dependent parameters (see the corresponding depth functions), which shall be forwarded to the depth-computing routines.
