csd_estimate | R Documentation |
csd_plot gives an estimate of the number of geographic clusters given a set of dispersal hypothesis and a suitability raster
csd_estimate(model, dispersal_steps = c(2, 4, 8, 16, 32, 64))
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. |
For more information about the Connectivity-Suitability-Diagram
see bam_clusters
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 contained in the tbl_df object.
