Dear List, I have n datsets that I would like to test for spatial dependence using the lm.LMtests function. I have computed a n by n row-standardised spatial weights matrix that I have imported into R workspace from a csv.-file. Running the lm.LMtests function I get an error message that the n by n matrix is not a listw object. How can I convert the matrix into a listw object?
?mat2listw All of this is described in detail in ASDAR. Roger
I would be grateful for any help. Sebastian
