DAISIE_margprobdist | R Documentation |
This function calculates the marginal distribution of the number of endemics and non-endemics and their sum for a given set of parameter values, a given mainland species pool size and a given set of times
DAISIE_margprobdist( pars1, pars2, tvec, initEI = c(0, 0), initprobs = NULL, pb = NULL )
pars1 |
Vector of model parameters: |
