[R-sig-Geo] simulation loop and creating weights

Greetings, In a simulation I'm running, I would like to create a series of listw weight matrices outside of the simulation loop. The appropriate inverse distance weights matrix I want to use is determined within the simulation loop using the sp.correlogram function. For instance there are 5

[R-sig-Geo] geoR likfit message

Greetings, I am revisiting some simulations that I ran about a year ago. When I run the likfit function from geoR; a message is returned that reads "kappa not used for the spherical correlation function". The simulations still run, but wasn't sure if this message indicates another problem th

[R-sig-Geo] collecting significance values in sp.correlogram

Greetings, I'm running a simulation and want to collect the p-values from the sp.correlogram in spdep (version 0.4-4). I've used the $res to collect the estimate and variance, but would like to collect the p-values "on the fly" in an intermediate step. Any suggestions? [[alternative

Re: [R-sig-Geo] Spatial simulation

I conducted similar simulations using invIrM in the spdep package. Dr. Anselin has a nice tutorial entitled Spatial Regression Analysis in R, A Workbook ( http://www.sal.uiuc.edu/stuff/stuff-sum/pdf/rex1.pdf ) (90 pp., 456K) at http://www.sal.uiuc.edu/stuff/stuff-sum/tutorials where I began to
