Hey Peter,
it is not necessary to use "factor(town)". I can just use "town" as the
name of the towns is already numeric.

Hey David,
Hey,
I just have trouble adding a object specific time trend with the
plm-package. I recieve the following error:
*
**"Error in model.frame.default(terms(formula, lhs = lhs, rhs = rhs,

I used the formula:

Hey Duncan,
thank you very much for your quick reply.
_My data used:_
1st column(town):1,1,1,1,1,1,1,1,1,1,1,1,2,2,2,...,11
2nd column(year):1,2,3,4,5,6,7,8,9,10,11,12,1,2,3...,12
3rd column (revenue):
4th colum (supply):
I have now renamed my colums and did the regression
wuhu, the plot is running now;)
I had to put three brackets instead of two at the end of the formula.
Thank you!

Hey Guys,
I just try to differentiate certain values in my plot by colour or symbol.
I have panel data with three dimensions (number of stations, revenue,
years). To integrate the third dimension (years) in the plot, I want to
differentiate the values(number of stations, revenue) by a certain
