st: Data Management Loop

[Toby <spiegeldesaster@googlemail.com>]

Hello Statalist,

i have a problem with the following data structure:

id type   x
1 1       1
2 2       2
3 1       3
4 2       4
5 1       5
6 2       6

Now I want to generate additional variables that include the x value
for the opposite type, so that the data looks like this:

id type   x   x_2   x_4    x_6   x_1    x_3   x_5
1 1       1    2      4        6
2 2       2    .       .        .         1     3         5
3 1       3    2     4         6
4 2       4    .       .        .         1     3         5
5 1       5    2     4         6
6 2       6    .       .        .         1     3         5

Until know I only have created a loop that generates this additional
variables, but I did not figured out how to disriminate between the
two type. Can anyone hive me a hint?

Kind regards,
Toby.
