as.svydesign2 {survey} | R Documentation

## 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.

### Usage

    as.svydesign2(object)
    .svycheck(object)

### Arguments

`object` | produced by `svydesign`

### Value

Object of class `survey.design2`
