GeNetIt is an R package for spatial graph-theoretic gravity modeling. The model framework is applicable for other types of matrix-based spatial flow (from-to) problems. Includes functions for constructing spatial graphs, sampling, summarizing associated raster variables and building unconstrained and singly constrained gravity models following Murphy et al., (2010).

As of version 0.1-6 all support of raster (RasterLayer, RasterStack) and sp (SpatialPointsDataFrame) class objects has ended, replaced by terra (SpatRaster) and sf (sf POINT) classes.

Available functions in GeNetIt 0.1-6 are:

| GeNetIt Function | Description | |:-----------------------------|:----------------------------------------------------------------------------------------| | adj.matrix | Creates binary adjacency matrix of from-to (joins) structure of graph | build.node.data | Build node data | compare.models | Compare competing hypothesis (models) | dmatrix.df | Distance matrix to data.frame | dps | dps genetic distance matrix for Columbia spotted frog (Rana luteiventris) | flow | Convert distance matrix to flow (1-d) | graph.metrics | Calculates a suite of metrics on the structure of the graph | graph.statistics | Raster statistics for edges (lines) with buffer argument for multi-scale assessment | gravity.es | Effect size for a gravity model | gravity | Gravity model | knn.graph | K Nearest Neighbor or saturated Graph | node.statistics | Raster statistics for nodes (points) | plot.gravity | plot generic for a gravity model object | predict.gravity | predict generic gravity model | print.gravity | print generic gravity model | ralu.model | Columbia spotted frog (Rana luteiventris) data for specifying gravity model. Note, the data.frame is already log transformed. | ralu.site | Subset of site-level spatial point data for Columbia spotted frog (Rana luteiventris) | rasters | Subset of raster data for Columbia spotted frog (Rana luteiventris) | summary.gravity | summary generic for gravity model objects | area.graph.statistics | Depreciated, please use graph.statistics with buffer argument
