runningratio2: Running ratio with adaptive window

In broman: Karl Broman's R Code

Running ratio with adaptive window

Description

Calculates a running ratio; a ratio sum(top)/sum(bottom) in a sliding window, but rather than a fixed-width window, use nearest positions to give some target denominator

Usage

runningratio2(pos, numerator, denominator, at = NULL, window_denom = 100)

Arguments

pos	Positions for the values.
numerator	Values for numerator in ratio.
denominator	Values for denominator in ratio.
at	Positions at which running ratio is calculated. If NULL, pos is used.
window_denom	Target denominator for window for calculating ratio

Value

A vector with the same length as the input at (or pos, if at is NULL), containing the running ratio.
