Dear all,

Does anyone know about packages or commands to calculate direct, indirect
and total impacts? I didn't find it on spml package.
package spdep has impacts methods for some models, see ?impacts :

library(spdep)
Loading required package: Matrix
methods(impacts)
[1] impacts.gmsar* impacts.sarlm* impacts.stsls*

and model fitting functions in the splm package use those in their own 
method:
library(splm)
methods(impacts)
[1] impacts.gmsar* impacts.sarlm* impacts.splm*  impacts.stsls*

so use that method in the same way.

Thank you.
