sln_add_node: Add node to spatial lines object

Description

Add node to spatial lines object

Usage

sln_add_node(sln, p)

Arguments

sln

A spatial lines (sfNetwork) object created by SpatialLinesNetwork

p

A point represented by an sf object the will split the route

Examples

# NOT RUN {
sample_routes <- routes_fast_sf[2:6, NULL]
sample_routes$value <- rep(1:3, length.out = 5)
rnet <- overline2(sample_routes, attrib = "value")
sln <- SpatialLinesNetwork(rnet)
p <- sf::st_sfc(sf::st_point(c(-1.540, 53.826)), crs = sf::st_crs(rnet))
sln_nodes <- sln2points(sln)
sln_new <- sln_add_node(sln, p)
route <- route_local(sln_new, p, sln_nodes[9, ])
plot(sln)
plot(sln_nodes, pch = as.character(1:nrow(sln_nodes)), add = TRUE)
plot(route$geometry, lwd = 9, add = TRUE)
# }
