5\title{Create a map of \code{dodgr} flows.}
6\usage{
7dodgr_flowmap(net, bbox = NULL, linescale = 1)
8}
9\arguments{
10\item{net}{A street network with a \code{flow} column obtained from
11\link{dodgr_flows_aggregate} or \link{dodgr_flows_disperse}}
12
13\item{bbox}{If given, scale the map to this bbox, otherwise use entire extend
14of \code{net}}
15
16\item{linescale}{Maximal thickness of plotted lines}
17}
18\value{
19Nothing; called for side-effect of producing plot.
20}
21\description{
22Create a map of the output of \link{dodgr_flows_aggregate} or
23\link{dodgr_flows_disperse}
24}
25\note{
26\code{net} should be first passed through \code{merge_directed_graph}
27prior to plotting, otherwise lines for different directions will be overlaid.

29\examples{
30graph <- weight_streetnet (hampi)
31from <- sample (graph$from_id, size = 10)
32to <- sample (graph$to_id, size = 5)
33to <- to [!to \%in\% from]
34flows <- matrix (
35 10 * runif (length (from) * length (to)),
36 nrow = length (from)
37)
38graph <- dodgr_flows_aggregate (graph, from = from, to = to, flows = flows)
39# graph then has an additonal 'flows` column of aggregate flows along all
40# edges. These flows are directed, and can be aggregated to equivalent
41# undirected flows on an equivalent undirected graph with:
42graph_undir <- merge_directed_graph (graph)
43\dontrun{
44dodgr_flowmap (graph_undir)
