find_zeros_cross: Find distance to first zero

In jpkeller/spconf: Computing Scales of Spatial Smoothing for Confounding Adjustment

Find distance to first zero

Description

For a set of distance and smoothing matrix values, determines the smallest distance that corresponds with negative value for each column of the smoothing matrix.

Usage

find_zeros_cross(D, S)

Arguments

D	Distance matrix, or a subset of columns from a distance matrix.
S	Smoothing matrix, or a subset of columns from a smoothing matrix.

Value

Vector of length equal to the number of columns in D and S. Each value is the smallest observed distance (from a column of D) that has a negative value in the corresponding column of S.
