od2odf(flow, zones)
flow |
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 |
zones |
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', based on a data frame containing
origin and destination cones (flow) that match the first column in a
a spatial (polygon or point) object (zones).
The function returns a data frame with coordinates for the origin and destination.
