plot.sfnetwork function

Plot sfnetwork geometries

Plot the geometries of an object of class sfnetwork.

## S3 method for class 'sfnetwork'
plot(x, draw_lines = TRUE, ...)

Arguments

• x: Object of class sfnetwork.
• draw_lines: If the edges of the network are spatially implicit, should straight lines be drawn between connected nodes? Defaults to TRUE. Ignored when the edges of the network are spatially explicit.
• ...: Arguments passed on to plot.sf

Returns

This is a plot method and therefore has no visible return value.

Details

This is a basic plotting functionality. For more advanced plotting, it is recommended to extract the nodes and edges from the network, and plot them separately with one of the many available spatial plotting functions as can be found in sf, tmap, ggplot2, ggspatial, and others.

Examples

oldpar = par(no.readonly = TRUE)
par(mar = c(1,1,1,1), mfrow = c(1,1))
net = as_sfnetwork(roxel)
plot(net)

# When lines are spatially implicit.
par(mar = c(1,1,1,1), mfrow = c(1,2))
net = as_sfnetwork(roxel, edges_as_lines = FALSE)
plot(net)
plot(net, draw_lines = FALSE)

# Changing default settings.
par(mar = c(1,1,1,1), mfrow = c(1,1))
plot(net, col = 'blue', pch = 18, lwd = 1, cex = 2)

# Add grid and axis
par(mar = c(2.5,2.5,1,1))
plot(net, graticule = TRUE, axes = TRUE)
