Panel Data Regression in R

Help, i'm really new to R and don't really know much about panel data. Your help would be much appreciated.

I wanted to do regression and it would follow Model Gravity for Trade theory. In the theory, there should be one country as a base so you could predict its trade flow in the future. I figure since it's a panel data, i can't create a column containing this country data since it would mess with other countries data. How could i do this? Should I separate this country data in a new sheet?

sorry for my bad english

Have no idea what you have just said. How many countries do you have in the data set? How many time points? Why do you think this is panel data?
