Compute Ratios

Description

Computes ratios from water-quality or other data and maintain the integrity of the data, as opposed to methods that use simple substitution

Usage

ratio(numerator, denominator)

Arguments

`numerator`	any valid vector that can be converted to class "mcens." Missing values are permitted but result in missing values in the output.
`denominator`	any valid vector that can be converted to class "mcens." Missing values are permitted but result in missing values in the output.

Details

Objects of class "qw" are converted to class "mcens" using the qw2mcens function, which preserves the minimum value of 0 for "less than" data rather than as.mcens, which converts the to left-censored values.
