mizer (version 3.4.0)

convert_density_units: Restate the units of a density in a different density measure

Description

The per-size factor is found in either of the two spellings mizer uses for it, 1/g and g^-1, and is then swapped for the size unit of the target measure. A density per logarithmic size carries no size unit at all — a number per log weight interval is just a number — so converting to one removes the factor instead: 1/g becomes dimensionless and g^-1/year becomes 1/year.

Usage

convert_density_units(units, from, to)

Value

The units expressed in the to measure.

Arguments

units

The units of the values, possibly NULL.

from, to

Density measures, see density_measures.

Details

Units that state no per-size factor are returned unchanged, since there is then nothing to identify as the size unit.
