Ray Shooting depth Bag

Description

Computes the Ray Shooting depth ISO of a point with respect to a bivariate data set.

Usage

getbag(x, y=NULL, factorsecondbag=2,...)

Arguments

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 bivariate observation. If it is a list, all components must be numerical vectors of equal length (coordinates of observations).
y	The data as a matrix, data frame or list. If it is a matrix or data frame, then each row is viewed as one bivariate observation. If it is a list, all components must be numerical vectors of equal length (coordinates of observations).
factorsecondbag	Factor of the second bag. Takes integer values. By default set to 2.
...	For future use.

Details

In dimension 2, calculates ray shooting depth of a given point with respect to the point set. Time complexity of the simple algorithms implemented is O(n log n). ISO

Value

Returns with respect to data set pt, the number of line segments interested by a ray from , minimum over all rays. ISO
