[R-sig-Geo] Problem with moran.test function

[Michael Haenlein]

Dear all,

I'm trying to estimate Moran's I using the moran.test function Below
please find the summary statistics for my network and key variable. In
doing so, I'm facing the issue that my estimation results in the
following error message:

Warning message: In moran.test(x, Network_): Out-of-range p-value:
reconsider test arguments

The results are as follows:

        Moran's I test under randomisation

data:  x
weights: Network

Moran I statistic standard deviate = NA, p-value = NA
alternative hypothesis: greater
sample estimates:
Moran I statistic       Expectation          Variance
             -Inf     -0.0002926544                NA

Could anyone please tell me what this error message means?

Is there a problem with my network and/ or with my key variable?

Thanks very much for letting me know,

Michael
