spd {meteR}

Species Power Distribution

Description

spd.meteESF calculates the distribution nu(e | N0, S0, E0), the distribution of average metabolic rates across for each species in a commmunity

Usage

spd(x)

## S3 method for class 'meteESF'
spd(x)

Arguments

x

an object of class meteESF.

Details

p

cumulative density function

q
