Hello I am trying to computes Moran's I autocorrelation coefficient of x giving a matrix of weights using the ape package. The null hypothesis of no correlation is tested assuming normality of the Moran's coefficient under this null hypothesis. I got a p-value=0
Does it mean that the p value is incredibly small that R cannot approximate it?
What is the lowest number that R displays before rounding it to 0? Can I change any options to get a number different than zero?
Thanks a lot
