Hello. I'm kind of new in R so you please forgive me if this is something really easy to but but i still don't find the solution. I want to plot a time series of production of several firms extracted from a panel data structure. I've tried with Stata but the most i achieved it's to plot a single time series for each firm, witch it's not what i want: I want every production time series in a single graphic. The other thing i could do it's to save the graphics for each firm separated and combine them but I have data from several countries and the quantity of firms varies from time to time and from country to country so I would like to control for both variables. Greetings and thanks for the all you could give me. -- View this message in context: http://www.nabble.com/Problem-Plotting-Production-Panel-Data-tp25481453p25481453.html Sent from the R help mailing list archive at Nabble.com.
