Is there a command that will give me the proportion of the time a variable is equal to a certain value? The command must accept weights. I'm looking for something like -tabcond-, from SSC, but that returns proportions as well as counts.

One option would be to -generate- a dummy equal to 1 when my variable is equal to my value and zero otherwise and then to use - svy: mean-, but I would prefer something that can be done in one line (and without generating a new variable). My variable is continuous, so I don't want to -svy: tab- the whole thing.
