Had you provided the output of sessionInfo(), it would be easier to say. 
My guess is that you are using sphet 1.7, and spdep 0.8-1. The use of 
eigenvalues in impacts measures was presented by Gianfranco Piras at the 
Spatial Econometrics meeting in June 2018, and implemented in spdep and 
sphet, but sphet has not been released since then. I just bumped the 
version number of sphet on R-Forge to 1.7-2, and hope that it will let you 
run install.packages("sphet", repos="http://R-Forge.R-project.org"), which 
is not possible at the moment (see 
https://r-forge.r-project.org/R/?group_id=477). If you can install the 
development version of sphet from source, check it out by:

svn checkout svn://svn.r-forge.r-project.org/svnroot/sphet/

and run R CMD build sphet, then R CMD INSTALL that .tar.gz file.
