rnet_merge: Merge route networks, keeping attributes with aggregating functions

Description

Merge route networks, keeping attributes with aggregating functions

Usage

rnet_merge(rnet_x, rnet_y, dist = 5, funs = NULL, sum_flows = TRUE, ...)

Value

An sf object with the same geometry as rnet_x

Arguments

rnet_x

Target route network, the output will have the same geometries as features in this object.

rnet_y

Source route network. Columns from this route network object will be copied across to the new network.

dist

The buffer width around rnet_y in meters. 1 m by default.

funs

A named list of functions to apply to named columns, e.g.: list(flow = sum, length = mean). The default is to sum all numeric columns.

sum_flows

Should flows be summed? TRUE by default.

...

Additional arguments passed to rnet_join.

Examples

# The source object:
rnet_y = route_network_small["flow"]
# The target object
rnet_x = rnet_subset(osm_net_example[1], rnet_y)
plot(rnet_x$geometry, lwd = 5)
plot(rnet_y$geometry, add = TRUE, col = "red", lwd = 2)
rnet_y$quietness = rnorm(nrow(rnet_y))
funs = list(flow = sum, quietness = mean)
rnet_merged = rnet_merge(rnet_x[1], rnet_y[c("flow", "quietness")],
                         dist = 9, segment_length = 20, funs = funs)
plot(rnet_y$geometry, lwd = 5, col = "lightgrey")
plot(rnet_merged["flow"], add = TRUE, lwd = 2)
