shift.left: Shift vector elements to the left

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 shifts vector elements to the left, filling the new last position with a specified value. 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

shift.left(v, last = NA)

Arguments

v	a vector
last	a value to be inserted at the last position after shifting

Details

All vector elements are shifted to the left: the original v[1] disappears, the original v[2] becomes the new v[1], etc. The new v[length(v)] value is set to last (defaulting to NA).

Value

The shifted version of v.
