Thanks for your answer Stefan, but I think cbind/rbind does not solve my problem. After reading ?cbind I realised that first I should convert all the dataset to panel separately, and then I will be able to cbind/rbind it. So the question is how to read in the following data from a file as a panel dataset country year1 year2 Germany var1 var1 Hungary var1 var1 that is to have: country year var1 Germany year1 value1 Germany year2 value1 Hungary year1 value1 Hungary year2 value1 if I understand well, then I can run pdata.frame on the latter with id=country and time=year moreover, I'll be able to cbind several var1, var2, etc data files into one panel dataset Viktor ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
