geonetwork | R Documentation |
Create an igraph
object with geospatial attributes for the
nodes.
geonetwork(edges, nodes, directed = TRUE, CRS = 4326)
edges |
data.frame. Edges list and attributes. See Details. |
nodes |
data.frame. Nodes list and attributes. See Details. |
directed |
logical. Default is to build a directed graph. |
CRS |
Coordinate Reference System, as a numeric or character code, an object of class [sf::sf] or [sf::sfc], or a 'src' object as built by function [sf::st_crs]. |
The first two columns in edges
must be character or factor,
and match the node names in the first column of the nodes
data.frame. The third column, if any, will be used as edge weights.
The remaining columns will be used as additional edge attributes.
The first column in nodes
must be character or factor and
provide node names or labels, not necessarily unique. Columns 2
and 3 must be numeric coordinates in the Coordinate Reference
System specified in CRS
.
An object of class geonetwork
, which also inherits
from igraph
.
e <- data.frame(from = c("A", "A"), to = c("B", "C"))
n <- data.frame(id = LETTERS[1:3], x = c(0, 0, 1), y = c(0, 1, 0))
geonetwork(e, n)
