Generate new group by id and other group in panel data

[Dimitrie Siriopol]

Dear all,
I know that the title is confusing, but I had no idea how to better describe my issue.
So, I have the following dataset:

id	group
1	-1
1	-1
1	-1
2	0
2	0
2	0
3	1
3	1
3	1
3	1
4	-1
4	1
5	-1
5	0

I would like to generate a new variable that would take different values, depending on the values from the group variable, per id.
So, if there are only -1, then the new variable will be 0 (or whatever number) for the respective person (in my example id 1 will have this value). If there are only 0 another number (id 2). If there are only -1 and 0 another number (id 5)... and so on.

Thank you,
Dimi

Agreeing with Amin's comment, you'll increase your chances of a useful answer by following the FAQ on asking questions - provide Stata code in code delimiters, readable Stata output, and sample data using dataex.

Just a guess, but egen g=group(id group) might be what you want.
