ustep: Calculate the unit step function value

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 calculates the unit step values by comparing input argument against a 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

ustep(v, thres = 0)

Arguments

v	a numeric vector
thres	a numeric threshold

Details

The unit step value is 1 if the input argument is greater than or equal to the threshold and 0 otherwise.

Value

A vector of unit step values for all input argument values from v.
