st: reshaping data

[Sascha Robert <sascha.robert@iew.unizh.ch>]

Hello

I would like to reshape some data. Now it looks something like this:

id    time    var
1     1       x
2     1       y
1     2       z
2     2       w

I would like to change it to

id    var_t1    var_t2
1     x         z
2     y         w

Any hints?

Kind regards,
Sascha
