Description Usage Arguments Details Author(s) Examples

View source: R/depth.R

Description

Computes the Projection depth of a point or vectors of points with respect to a multivariate data set.

Usage

1
depthProjection(u, X, ndir = 1000, threads = -1)

Arguments

u

Numerical vector or matrix whose depth is to be calculated. Dimension has to be the same as that of the observations.

X

The data as a matrix, data frame or list. If it is a matrix or data frame, then each row is viewed as one multivariate observation. If it is a list, all components must be numerical vectors of equal length (coordinates of observations).

ndir

number of directions used in computations

threads

number of threads used in parallel computations. Default value -1 means that all possible cores will be used.

...

currently not supported.

Details

Irrespective of dimension, Projection and Tukey's depth is obtained by approximate calculation.

Returns the depth of multivariate point u with respect to data set X.
