R help - Jan 2015 - Weighted Kaplan-Meier estimates using survey::svykm and survival::survfit

Hello, is there a way to convert a svykm object returned by survey::svykm
into a survfit object? The reason I am asking is that plot.survfit can plot
different transformations of survival curves, a functionality that is
currently not afforded by plot.svykm.
Thanks!
Youyi
