csd_estimate {bamm}

csd_estimate: Estimate the connectivity suitability and dispersal plot

Description

csd_plot gives an estimate of the number of geographic clusters given a set of dispersal hypothesis and a suitability raster

Usage

csd_estimate(model, dispersal_steps = c(2, 4, 8, 16, 32, 64))

Arguments

model

A raster model or a setA object representing the suitability model

dispersal_steps

A numeric vector with elements representing the dispersal hypothesis to test.

Details

For more information about the Connectivity-Suitability-Diagram see bam_clusters

Value

A list of length three. The first element contains the Connectivity- Suitability-Diagram information estimated for each element in the vector of dispersal_steps. The second is tbl_df object with a summary of the number of cluster of each dispersal step and the mean number of connected clusters. The last element is base plot showing the information cointained in the tbl_df object.
