Convert to SF

Converts an igraph object into two sf objects

Usage

convert_sf(g, lat, lon, jitter = 0, landscape = TRUE, crs = 3857)

Arguments

g

igraph network

lat

attribute that gives latitude

lon

attribute that gives longitude

jitter

amount of jitter to add

landscape

if true changes bounding box to be landscape

crs

default CRS to use, using Web Mercator

Value

list of edges_sf and nodes_sf
