[R] panel data and model selection

[amatoallah ouchen]

Good day R-listers,
I'm working with a panel dataset, i've used many   models  ,
homogeneous (fixed effect, pooled ols and Driscoll and Kraay)
heterogeneous (swamy random coefficients)  and  would like to do a
post-estimation to select the model that best fit  my regression. is
there any method, command that may allow me to do this in R?
Any hint will be highly appreciated
Ama.
