I have two datasets that I am trying to merge. One dataset (A) is uniquely
identified by three variables (ID YEAR SEMESTER). The other dataset is
uniquely identified by four variables (ID YEAR SEMESTER GRANTTPYE). In the
second dataset (B) students can get more than one GRANTTYPE in a given
semester so it is important to keep this factor.
What I've been trying to do is to collapse the second dataset (B) so that it
is identified by only three variables then I can merge it with dataset A.
I think it's clearest if I can illustrate with a simple example...
Current form of dataset B:
ID YEAR SEMESTER GRANTTYPE AWARDAMT
1 1990 Fall 1 500
1 1990 Fall 0 200
Form that I am attempting to convert dataset B into:
ID YEAR SEMESTER GRANTTYPE1awardamt GRANTTYPE2awardamt
1 1990 Fall 500 200
The only form that I have been able to achieve so far:
ID YEAR SEMESTER GRANTTYPE1awardamt GRANTTYPE2awardamt
1 1990 Fall 500 .
1 1990 Fall . 200
How do I "squish" the data so that I end up with one entry per kid per year
per term?
Thanks,
Jennifer
