Impacts code after gstslshet

 Hi,

 My name is Germ?n Iz?n. I am currently working on a project in which I am
 estimating a SARAR specification using the gstslshet function. After
 estimating this model I tried estimating the marginal effects using the
 impacts function but I get the following error: ?Error in
 spdep::intImpacts(rho = rho, beta = beta, P = P, n = n, mu = mu, :
 argument "evalues" is missing, with no default?. I get the same message
 using the columbus data. I do not get this error after estimating a
 spatial lag model (e.g., lagsarlm). I would truly appreciate any help with
 this. Thank you!

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.
