[R-sig-Geo] How to extract just the Moran's I values using moran.test{spdep}?

[Xingli Giam]

Hello List,

I hope to extract the Moran's I values using moran.test{spdep} to manually plot
a correlogram. However calling the value $estimate produces not just the
Moran's I, but also its expectation and variance under method assumption. Is
there a way I can extract just the Moran's I so that I can place it in a
dataframe against the binned distance classes to plot a correlogram?

Many thanks!
