As you say, -merge- the two files. Which "repeats" are you referring to?

Subject: st: Subset of data into new file

Hi all,

I have data about groups, from which I am calculating means for the groups.

Indiv Group Size GroupAvgSize
1        a          2           4
2        a          4           4
3        a          6           4
1        b          3           3
2        b          4           3
3        b          2           3


Then, I want to merge the group avg size with a larger set of data
containing the same groups, but a larger set of individuals (where
size is not recorded).

Indv    Group
1           a
2           a
3           a
4           a
5           a
1           b
2           b
3           b
4           b
5           b

Is there a way to do this without exporting the data with GroupAvgSize
to a spreadsheet, where I could crop out the repeats?

Thanks!

-Steve
