Although you don't have coordinates, there has to be some kind of information
on spatial relationships. (I am likely saying the same thing as Roger.)
Let me see if I have this right. Some large area is partitioned into cells
(polygons in an ArcInfo shape file?) and, within each
I never used it, but I beleave that it is a job for mantel.rtest() available
on ade4 package.
In fact Farrar are right, you will neet the XY coordinates. Give a look at
Legendre Legendre text book.

Thanks David and Milton for replies. No, I don't have the coordiates.
In other words, my data are not point data. But I think there is a way
to test of spatial dependence for areal data or lattice data. In this
case, the variable of interest is typically the average value of an
area instead of a

In addition to the 25 numbers, I assume you have coordinates of each field.
Otherwise, I don't understand what you are trying to do. I think ecologists
like to use a test due to Mantel in this situation.
The prefix auto means self, of course, the idea being that measurements
