plotgraph: Plotting the spatial graph

In gDefrag: Graph-Based Landscape De-Fragmentation

Description

Function to plot the spatial graph

Usage

plotgraph(nodes, edges, land_polyg, scale_nodes = 10, col_nodes = "darkblue", 
col_labels = "darkblue", cex_labels = 1, main = "Graph")

Arguments

nodes	Output of node.creation.
edges	Output of edge.creation.
land_polyg	SpatialPolygonsDataFrame with the polygons defined by roads and the study site limits.
scale_nodes	Node size scaling factor for correct viewing in the plot.
col_nodes	Node colour.
col_labels	Labels colour.
cex_labels	Text labels font size.
main	Main plot title.

Details

Produces a plot of the study site, nodes and edges with the prioritization order.

Value

This function plots the spatial graph.

Examples

data(road_P)

#Obtaining nodes
out1 <- node.creation(land_polyg = road_P, value_col = "forest_sum", 
scale_nodes = 10, col_nodes = "pink", cex_labels = 1)

#Obtaining edges
out2 <- edge.creation(nodes = out1, land_polyg = road_P, 
min_length = 0, min_pol_area = 0)

#Prioritize
out3 <- prioritize(nodes = out1, edges = out2, method = "value")

#Plotting results
plotgraph(nodes = out1, edges = out3, land_polyg = road_P, main = "Habitat value")
