[R] question regarding panel data analysis

[amatoallah ouchen]

Good day R-users,
 I apologize for asking such an elementary question, but I could not
 find an adequate response . I'm currently running a panel data analysis
i've used the plm package to perform the Tests of poolability as
results intercepts and coefficients are assumed different. so my
question is should give up the panel analysis in my case or is there
any alternative methodology or transformation i can use instead??

Any hint would be highly appreciated

thanks a lot in advance.

Ama
