mob_indic: Shape mobility indicators
In Geographie-cites/toyspace: bla bla bla

Description Usage Arguments Value

This function allows you to create an sf object containing mobility indicators in each polygons using a data.frame of flows

1	mob_indic(tabflows, idori, iddes, idflow, pol, idpol, poptab)

`tabflows`	A data.frame of flows between origins and destinations (long format matrix containing, at least, 3 column : 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
`pol`	An sf object of the cities
`idpol`	A character string identifier of cities
`poptab`

An sf object of the cities with mobility indicators for each polygons

There are 4 mobility indicators : - Self-Sufficiency (SelfSuff) : it refers to the ratio between internal flows and the amount of workers. It expresses the local balance between workers and jobs with a low rate of outflows (from 0 to 1, where 0 express dependency and 1 sufficiency) - Dependency (Dependency) : it refers to the ratio between internal flows and the population of the city. It expresses the level of dependence of a city in terms of job offer. - Mobility (Mobility) : it refers to the ratio between inflows and outflows on one hand, and the amount of workers on the other. It expresses the density of displacements in a city. - Relative Balance (RelBal) : it refers to the ratio between inflows less outflows on one hand and the population of the city on the other. It expresses the degree of polarization of a city, thus its attractiveness in terms of employment. - Percentage at Origin (perOri) : it refers to the percentage of total worker living in the city - Percentage at Destination (perDes) : it refers to the percentage of total worker working in the city - Percentage of InternalFlow (perIntra) : it refers to the percentage of total worker living and working in the city
