Subject: Cannot have zero distances in "corSpatial"
Hi folks
data structure: plots nested in sites, and observations nested in plots. both site and plots used as random factors
When running a mixed model (lme4) I founded spatial autocorrelation on model residuals, thus, I tried nlme mixed models inclunding a spatial structure (e.g. corr=corExp(...)), since I have repeated measures at the same point (then, with the same coordinates) the package is unable to run, giving the error: Cannot have zero distances in "corSpatial" in nlme
It seems to be a common and unsolved problem

It is my first time here, sorry for any mistake in my post.
Thanks
