Hi, Bolker, nice to meet you. 
I?m doing my master degree at University of S?o Paulo. I?m traing to analize how the temperature affects the sexual traits. I have a morfological data from 21 populations along to east cost of Brazil. For each population I have just one data of temperture and one coordenates (Lat, Lon). And I want see the temperatura efect in male and females (like an ANCOVA in a simple case). So, I don?t know what is kind of analise that I need to do, because, all that I tried to do, result in the same problem: 


"Error in getCovariate.corSpatial(object, data = data) : 
cannot have zero distances in "corSpatial" ". 


Plesae, I'd greatly appreciate advice on the matter. 


A hug, Soly

Dear Soly,

A workaround is to add some random noise to the locations.

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
