Dear list members:

    I was using the function localmoran.sad() in SPDEP package. Since I am
interested in the calculation of the star shaped weight list (Vi) of each
location, I set the save.Vi = TRUE. However, after I obtained the
saddlepoing approximated local Moran's I object (say, locmsad), the result
I got from using locmsad[[1]]$Vi is always "NULL". Does anybody have any
idea what I have done wrong? Thanks in advance.
