Reference distance filter

Description

filter_ref computes the reference distance filter.

Usage

filter_ref(dist, groups_ind, ref, ...)

Arguments

dist	The distance matrix.
groups_ind	A vector of group names each of the samples belongs to.

...	Additional arguments.

Details

Reference distance filter function is defined as f(x_i;y,g) = 1-\textrm{median}_{y_j=g} d(x_i,x_j), where

Value

A matrix object of filter values.
