I am looking for R packages that create a moran's I correlogram with ordinal data. my data format is x , y coordinates with a z values that ranges between 0-4. another concern i have is that my sample size is 250 and over 60% have a z value of 0. So i am concerned that the uneven nature of the z values will show autocorrelation when it is simply a matter that most of the data points have this value. Your advice/ thoughts are appreciated. Thanks Jenn
