In skgrange/emitr: Tools to Help With On-Road Vehicle Emission Data Analysis

Description

Functions to help calculate fuel specific emissions for various pollutants using their ratio to CO[2].

Usage

pollutant_ratio_to_fuel_specific_emission(ratio_pollutant, pollutant,
  ratio_co, ratio_hc)

read_molar_mass_table()

pollutant_to_co2_ratio(pollutant, co2)

nox_as_no2_equivalent(no, no2)

Arguments

ratio_pollutant	Ratio of pollutant to CO[2].
pollutant	In pollutant_ratio_to_fuel_specific_emission, a string representing which polluant is being transformed, e.g. "no". pollutant_ratio_to_fuel_specific_emission uses this string to find the correct molar mass. In pollutant_to_co2_ratio, it is the variable which is to be transformed.
ratio_co	Name of CO/CO[2] ratio variable.
ratio_hc	Name of HC/CO[2] ratio variable.
co2	Name of CO[2] ratio variable.
no	Name of NO ratio variable.
no2	Name of NO[2] ratio variable.

Value

Numeric vector or for read_molar_mass_table, a data frame.
