R-help Digest, Vol 157, Issue 25
Thanks to Boris Steipe, Jim Lemon and Ivan Calandra for replying. I messed up while copying, there are equal number of values for each country. @ Ivan, In case there were different number of values, and we wanted to fill in with 1) NA, or 2) "average of the rest of values" in the missing values, how would we "impute" such data. Thanks again /
