All,

I have three columns of data: id, date, hab. I am trying to set up a matrix
that has the id as the rows, date as columns, and the hab value as the data
values.  Each id/date combination can only have one hab value.  I would like
for it to look something like this"
         date 1, date 2, date 3.
id
0001     2        1         2
0002     3         5        6

I don't know how to set this up properly. I am pretty sure dates cannot be
used in a matrix, but I can easily convert this to an integer. I am mainly
unsure of the functions to use to do this operation.

Thank you
