Sample parameter data frame number 2

param2.Rd

Sample data frame, as produced by parameter.estimate. These parameters are to be passed to spom. These are based upon those computed for Cabrerae's vole in the paper Mestre et al. (2017) (see references).

Usage

data(param1)

Format

A data frame with 4 rows displaying the four parameters (alpha, x, y, e) to be passed to spom:

  • alpha - Parameter relating extinction with distance.

  • y - Parameter y in the colonization probability.

  • e - Parameter defining the extinction probability in a patch of unit area.

  • x - Parameter scaling extinction risk with patch area.
