## Survey design weights

### Description

Extract weights from a survey design object.

### Usage

    ## S3 method for class 'survey.design'
    weights(object, ...)
    ## S3 method for class 'svyrep.design'
    weights(object,
    type=c("replication","sampling","analysis"), ...)
    ## S3 method for class 'survey_fpc'
    weights(object,final=TRUE,...)

### Arguments

`object` | Survey design object
`type` | Type of weights: `"analysis"` combines sampling and replication weights.
`final` | If `FALSE` return a data frame with sampling weights at each stage of sampling.
`...` | Other arguments ignored

### Value

vector or matrix of weights

### Examples

    data(scd)

    scddes<-svydesign(data=scd, prob=~1, id=~ambulance, strata=~ESA,
                     nest=TRUE, fpc=rep(5,6))
    repweights<-2*cbind(c(1,0,1,0,1,0), c(1,0,0,1,0,1), c(0,1,1,0,0,1), c(0,1,0,1,1,0))
    scdrep<-svrepdesign(data=scd, type="BRR", repweights=repweights)

    weights(scdrep)
    weights(scdrep, type="sampling")
