Extract coordinates from OD data
od2odf(flow, zones)
A data frame representing origin-destination data.
The first two columns of this data frame should correspond
to the first column of the data in the zones. Thus in cents_sf()
,
the first column is geo_code. This corresponds to the first two columns
of flow()
.
A spatial object representing origins (and destinations if no separate destinations object is provided) of travel.
Origin-destination (OD) data is often provided
in the form of 1 line per OD pair, with zone codes of the trip origin in the first
column and the zone codes of the destination in the second column
(see the vignette("stplanr-od")
) for details.
od2odf()
creates an 'origin-destination data frame', with columns containing
origin and destination codes (flow
) that match the first column in a
a spatial (polygon or point sf
) object (zones
).
The function returns a data frame with coordinates for the origin and destination.
