TieBreakerFunction: Function for breaking tied votes

In ArdernHB/KnnDist: Kernal Nearest Neighbour classification with distance inputs

Description

This function is primarily for use in other k-NN functions. It takes a vector and applies the chosen tiebreaker method. This includes either randomly selecting one of the tied groups, returning all groups collapsed into a single character string, or returning 'UnIDed'.

Usage

TieBreakerFunction(X, TieBreaker)

Arguments

X

a vector of the tied classifications to be considered.

TieBreaker

is the method used to break ties if there is no majority resulting from K. Three methods are available('Random', 'Remove' and 'Report'): Random randomly returns one of tied classifications; Remove returns 'UnIDed' for the classification; Report returns a the multiple classifications as a single character string with tied classifications separated by '_'. NOTE: for correct cross-validation proceedures the results of both Report will be considered an incorrect identification even if one of the multiple reported classifications is correct.

Value

Returns a character string of the identification based on the chosen tiebreaker method.
