## Arguments

veh Numeric or data.frame of Vehicles with untis 'veh'. Numeric which can be either, daily mileage by age of use with units 'lkm', number of trips or number of proc. When it has units 'lkm', all the emission factors must be in 'g/km'. When ed is in g/day, x it is the number of days (without units). When hotfi, hotc or warmc are in g/trip, x it is the number of trips (without units). When hotfi, hotc or warmc are in g/proced, x it is the number of proced (without units). average daily evaporative emisisons. If x has units 'lkm', the units of ed must be 'g/km', other case, this are simply g/day (without units). average hot running losses or soak evaporative factor for vehicles with fuel injection and returnless fuel systems. If x has units 'lkm', the units of ed must be 'g/km', other case, this are simply g/trip or g/proced average running losses or soak evaporative factor for vehicles with carburator or fuel return system for vehicles with fuel injection and returnless fuel systems. If x has units 'lkm', the units of ed must be 'g/km', average cold and warm running losses or soak evaporative factor for vehicles with carburator or fuel return system for vehicles with fuel injection and returnless fuel systems. If x has units 'lkm', the units of ed must be 'g/km', fraction of gasoline vehicles with carburator or fuel return system. Fraction of trips finished with hot engine Character; Add columns with information to returning data.frame Numeric; montly profile to distribuite annual mileage in each month. Logical; To show more information

## Value

numeric vector of emission estimation in grams

## Note

When veh is a "Vehicles" data.frame, emission factors are evaluated till the number of columns of veh. For instance, if the length of the emision factor is 20 but the number of columns of veh is 10, the 10 first emission factors are used.
