flows - Flow Matrix Selection with Statistics and Visualisation
The analysis and representation of flows often presuppose
a selection to facilitate interpretation. Various methods have
been proposed for selecting flows, one of the most widely used
being based on major flows: it selects only the most important
flows, absolute or relative, on a local or global scale. These
methods often highlight hierarchies between locations, but the
loss of information caused by selection is rarely taken into
account. We propose statistical indicators to assess the loss
of information and the characteristics of selected flows. We
provide functions that select flows (main, dominant or major
flows), provide statistics on selections and offer
visualizations in the form of maps and graphs. See Beauguitte
et al (2015) <doi:10.4000/netcom.2134>.
