Plot a gPath object

This method plots a gPath object, which is the output of the dijkstraBetween, polygonBetween and dijkstraFrom functions.

Usage

# S3 method for class 'gPath'
plot(x, col = "rainbow", lwd = 3, seed = NULL, ...)

# S3 method for class 'gPath'
print(x, ...)

Arguments

x

a gPath object

col

a character string indicating a color or a palette of colors to be used for plotting edges.

lwd

a numeric value indicating the width of edges.

seed

an optional integer value to set the seed for random color generation when col = "rainbow".

...

further arguments passed to geo.segments.

Value

NULL.

Functions

• print(gPath): Print a summary of a gPath object

Examples

hgdp.sub <- hgdp[getData(hgdp)$Population %in%
  c("French", "Balochi", "BantuKenya", "Papuan", "Pima")]
hgdp.path <- dijkstraBetween(hgdp.sub) # compute shortest path

## plotting
plot(worldgraph.40k, reset = TRUE, pch = "")
#> Spherical geometry (s2) switched off
#> Spherical geometry (s2) switched on
points(hgdp.sub, lwd = 1) # plot populations
plot(hgdp.path) # plot the path


## printing
print(hgdp.path)
#> 
#> === gPath object ===
#> 
#>  number of paths: 10 
#> 
#>  available paths (id_origin:id_destination): 24988:16798 24988:7348 24988:40768 ...
#> 
#> each path, accessible with [[]] has elements 'length', 'path_detail' and 'length_detail'
#> x and y coordinates of all nodes are stored as an attribute 'xy'; see ?gPath for details
