Rose diagram

Description

Rose diagram to assess the spatial changes of a variable throught time.

Usage

roseDiagram(t1,t2,listw)

Arguments

t1	A numeric vector. The value of the variable of interest at the beginning of the time period.
t2	A numeric vector. The value of the variable of interest at the beginning of the end time period.
listw	List of spatial weights as returned by nb2listw

Details

This function plots a Rose Diagram as suggested by Ray, Murray and Anselin (2010), in order to assess changes in the spatial distribution of a variable between two distinct time periods.
