meteNu {meteR}

Equation of the PMF for the METE species metabolic rate distribution

Description

meteNu is a low level function to calculate the value of \nu(e | N_0, S_0, E_0) (the distribution of metabolic rates/power across all species in a commmunity) at the given value of e; vectorized in e.

Usage

meteNu(e, la1, la2, Z, S0, N0, E0)

Arguments

e

the value (metabolic rate/power) at which to calculate \Psi

la1, la2

Lagrange multipliers

Z

partition function

S0

Total number of species

N0

Total number of individuals

E0

Total metabolic rate

Details

Typically only used in spd.meteESF and not called by the user.

Value

numeric vector of length equal to length of e
