rsplot: Ray Shooting depth Bag

Description

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

Usage

rsplot(x, y=NULL, factorsecondbag=2,mring=T,...)

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 for second bag set to 2 by default.

mring

Boolean value set to TRUE by default.

...

For future use.

Value

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

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
