[R] Subpopulations in Complex Surveys

[TyagiAnupam@aol.com]

Hi, 
is there a way to analyze subpopulations (e.g. women over 50, those who 
answered "yes" to a particular question) in a survey using Survey package? 
Other packages (e.g. Stata, SUDAAN) do this with a subpopulation option to 
identify the subpopulation for which the analysis shoud be done. I did not 
see this option in the Survey package. Is there another way to do this?
