create.stochastic.landscape: Create stochastic landscape

In akeyel/spatialdemography: A Spatially Explicit Metacommunity Model

Description

Create a stochastic landscape for the stochastic plants model using a copula function In this case, it creates correlated distributions between a log-normal function (fertility) and a beta distribution (stochastic survival)

Usage

create.stochastic.landscape(run.path, my.lyrs, s.lbl, correlation, n, p, fxs,
  fxs.means, fxs.vars)

Arguments

run.path	Path for the model run
my.lyrs	Layers to include in the landscape
s.lbl	A label
correlation	Desired correlation level (will not be exact)
n	Number of samples to generate (1 per time step)
p	Number of cells in the landscape
fxs	Vector of functions for the copula
fxs.means	Vector of means for the copula, in same order as functions
fxs.vars	= Vector of variances/sd for the copula, in same order as above

Note

Requires copula package. Cells in the landscape will be generated independently of one another.
