In ncss-tech/sharpshootR: A Soil Survey Toolkit

Summarize Spatial Adjacency of Polygon Fabric

Description

This function utilizes the spdep and igraph packages to evaluate several measures of spatial connectivity.

Usage

polygonAdjacency(x, v = "MUSYM", ...)

Arguments

x	sf object containing simple polygon features, some of which should share edges
v	character, name of column in attribute table describing map unit labels
...	additional arguments passed to spdep::poly2nb()

Details

Examples are presented in this tutorial.

Value

a list containing:

• commonLines: an integer vector of feature IDs, describing polygons sharing edges and values of v (map unit labels)

• adjMat: weighted adjacency matrix, suitable for visualization with plotSoilRelationGraph()
