Dear friends, I received a dataset of point data, organized in the following way: a couple of coordinates and a column of "crop classes codes", three columns. I would like to compute something similar to the Moran index for each crop class code. How can I carry out such task in R?
spdep::joincount.multi() and spdep::joincount.test(). and read the references on the help pages. See eg. https://keen-swartz-3146c4.netlify.com/area-data-and-spatial-autcorrelation.html#measures-of-spatial-autocorrelation Roger
thanks in advance emanuele
