[R-sig-Geo] Eigenvalues in Eigenvectors - spatial correlation and spatial instrumental variables

Hi Everybody,

Recent convert and newcomer. I am interested in exploring the use of
eigenvalues as synthetic instrumental variables in the manner of Le
Gallo and Paez (2013). To do this I need to access the actual
eigenvalues in eigenvectors.  I am aware of the 2009 r-sig-geo
communication regarding potential to use ME() within spdep and the offer
of Professor Bivand to add eigenvalues as an attribute of the output
object when requested.  My question is whether this or any other
mechanism is available to specify eigenvalues within spdep as I do not
think this is currently an option and I cannot identify the code to
implement the adjustment offered in 2009?

Many Thanks

JimT
