GeoModel class

A reference class to represent results of dispersal models.

Slots

amatrix

A square adjacency matrix that represents the likely movement of a species between locations. In this adjacency matrix, rows and columns are the identification of the locations, and each entry indicates the relative likelihood of a species moving between a pair of locations. An adjacency matrix is produced for each unique value of the dispersal parameters chosen.

index

A raster object representing the habitat connectivity index of the locations in the selected region. Note that connectivity is calculated based on a weighted sum of the network metrics chosen by the user. A raster object is produced for each unique value of the dispersal parameters chosen.

hdthreshold

A numeric value representing the threshold for habitat availability (e.g., cropland density or host density) used in the sensitivity analysis.

aggregation

A character value representing the spatial aggregation method used for aggregating the habitat availability map before conducting the sensitivity analysis.

linkthreshold

A numeric value representing the threshold for the link weights used to calculate habitat connectivity of each location. Note that link weights indicate the relative likelihood of a species moving between locations (nodes) and correspond to the entries in the adjacency matrix.

beta

A numeric value representing the beta parameter. The beta parameter is the dispersal parameter in one of two dispersal kernel models (the inverse power law model) included in geohabnet.

gamma

A numeric value representing the gamma parameter. The gamma parameter is the dispersal parameter in one of two dispersal kernel models (the negative exponential model) included in geohabnet.
