Rebecca,

You can use the -svmat- command to create a variable from a matrix.  From
the examples given previously

    webuse highschool, clear
    svyset county [pweight=sampwgt], strata(state) vce(linearized)
    svy: mean weight, over(sex)
    matrix means =  e(b)
    matrix list means

    svmat means     // <-- This line creates two new variables

I hope this is helpful.
