as.svydesign2 {survey}

Update to the new survey design format

Description

The structure of survey design objects changed in version 2.9, to allow standard errors based on multistage sampling. as.svydesign converts an object to the new structure and .svycheck warns if an object does not have the new structure.

You can set options(survey.want.obsolete=TRUE) to suppress the warnings produced by .svycheck and options(survey.ultimate.cluster=TRUE) to always compute variances based on just the first stage of sampling.
