gaussian | R Documentation |
Bivariate Gaussian function useful for simulating the response of a species to two environmental variables. The function is standardized so that it yields a value of 1 when the covariates are at their "optimal" values. The default values produce a univariate Gaussian function centered on 0 with unit variance.
