In 42n4/dmr.util: A package with utility functions used in the book Cichosz, P. (2015): Data Mining Algorithms: Explained Using R

Description

This function finds in an input numeric vector the closest (greatest) value below a specified threshold. It is used in examples presented in the book Cichosz, P. (2015): Data Mining Algorithms: Explained Using R. See Appendix B or http://www.wiley.com/go/data_mining_algorithms for more details.

Usage

closest.below(v1, v2)

Arguments

v1	a numeric vector of threshold values
v2	a numeric vector of input value

Details

For each threshold value in v1, the greatest less input value from v2 is found and returned.

Value

A numeric vector of the same length as v1, containing for each element of v1 the greatest less value from v2 or -Inf if no such value exists.
