s_e_points: Derives a subset of integers from a given set

In IDetect: Isolate-Detect Methodology for Multiple Change-Point Detection

Description

This function finds two subsets of integers in a given interval [s,e]. The routine is typically not called directly by the user; its result is used in order to construct the expanding intervals, where the Isolate-Detect method is going to be applied. For more details on how the Isolate-Detect methodology works, see References.

Usage

s_e_points(r, l, s, e)

Arguments

r	A positive integer vector containing the set, from which the end-points of the expanding intervals are to be chosen.
l	A positive integer vector containing the set, from which the start-points of the expanding intervals are to be chosen.
s	A positive integer indicating the starting position, in the sense that we will choose the elements from r and l that are greater than s.
e	A positive integer indicating the finishing position, in the sense that we will choose the elements from r and l that are less than e.

Value

e_points A vector containing the points that will be used as end-points, in order to create the left-expanding intervals. It consists of the input e and all the elements in the input vector r that are in (s,e).

s_points A vector containing the points that will be used as start-points, in order to create the left-expanding intervals. It consists of the input s and all the elements in the input vector l that are in (s,e)
