Subject:      merge two datasets by year and id and also get the data for the
              previous two years
Content-Type: text/plain; charset=ISO-8859-1

Hi,

There are only two variables in one dataset, which is the id and year
(only one year, for example year 1986). The other datasets contains
id, many years (year1984 to year2003) and other varibles. If I want to
merge these two datasets to get the results for those ids in the first
dataset and years not only 1986, but also two years before that (i.e.,
year 1985 and 1984), how can I do this?

Thanks a lot!
