Codispersion Map for Rectangular Grids
The codispersion coefficient quantifies the association between two spatial processes for a particular direction (spatial lag) on the two-dimensional space. The R function hcodisp.map provides a graphical tool called codispersion map to visualize the spatial correlation between two sequences measured for regular lattices on the plane.

To create the Dynamically Loaded (DL) library, unpack the gzip file hcodisp.map.tar.gz
, next using the console prompt move to the created directory and enter:
R CMD SHLIB -o hcodisp.so *.c
To use this funtion, start R and enter:
source("hcodisp.map.R")
dyn.load("hcodisp.so")
z <- hcodisp.map(x, y)
