cbd_city: DF transform to CBD urban model

In Geographie-cites/toyspace: bla bla bla

Description

This function allows you to change the origins and destination of flows stored into a dataframe to simulate a Central Business District urban model. City considered as the main city of the region is designed as candidate and flows (destinations only) are moved from non-candidate cities to the candidate city. The origins are moved into from the candidate city to the non-candidate city, so that every jobs are in the main city, and workers in the suburbs.

Arguments

pol	An sf object of the cities
idpol	A character string of the column containing the id of the pol object

tabflows	A data.frame of flows between origins and destinations (long format matrix containing, at least, origins, destinations, flows)
idori	A character string giving the origin field name in tabflows
iddes	A character string giving the destination field name in tabflows
idflow	A character string giving the flow field name in tabflows
