In rsdepth: Ray Shooting Depth (i.e. RS Depth) Functions for Bivariate Analysis

Bivariate RS Rings

Description

Computes the Ray Shooting rings of a bivariate data set.

Usage

rstinterval(pt, beta=c(0.90), sampleSize=c(250), M=c(50),clr=FALSE, ...)

Arguments

pt	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). Only 2-dimensional data is acceptable in this version.
beta	beta is a parameter between 0 and 1 determines the accuracy of the interval. Set to 0.90 by default.
sampleSize	Size of the sample data set.
M	Size of test data set.
clr	Clear the canvas before use or not. Boolean and set to FALSE by default
...	Reserved for future use.

Details

This function creates a two dimension generalization of confidence intervals of data. A bag that contains beta fraction of data points is constructed.

Value

Should not return anything
