[R] stochastic growth rate (package biopop)

h term of my matrix), I want to sample this parameter from a beta function at each time-step {e.g., betaval(0.5, 0.05)}. Then I want to run the model for 1000 time steps (or more) and estimate the asymptotic stochastic growth rate. Is there a command that enable this kind of modelling? Thank you,

[R] Elasticity in Leslie Matrix

analysis" avaliable in package "popbio" provides sensibility matrix and elasticity matrix (same dimension than A). I would like to know if there is a way to calculate separetely the elasticity of sigma, s0, f1, f2, s and v ? Thanks and regards, privalan -- View this me
