RS Depth calculation
Computes the Ray Shooting depth of a point with respect to a bivariate data set.
Numerical vector whose depth is to be calculated. Data needs to be 2-dimensional.
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).
For future use.
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).
Returns the exact depth of bivariate point
q with respect to data set
pt, the number of line segments interested by a ray from
q, minimum over all rays.
