get_n0 {miLAG}

get_n0

Description

Gets the initial biomass to relate to

Usage

get_n0(biomass, n0_method)

Arguments

biomass

vector of biomass (chronologically ordered as in growth curve)

n0_method

"first.observation" if the first point is taken as the initial biomass or "minimal.observation" if the minimal biomass is taken is the initial point. In "healthy" growth curves these options should be equivalent but sometimes a drop in OD/biomass is observed at the beginning of a growth curve. In this case it is not obvious what to assume the initial biomass is.

Value

a value of the initial biomass (either the first observation or the minimum value depending on the parameter N0.method)
