Examples

data(api)
dclus1<-svydesign(id=~dnum, weights=~pw, data=apiclus1, fpc=~fpc)
svykappa(~comp.imp+sch.wide, dclus1)

dclus1<-update(dclus1, stypecopy=stype)
svykappa(~stype+stypecopy,dclus1)


(kappas<-svyby(~comp.imp+sch.wide,~stype,design=dclus1, svykappa, covmat=TRUE))
svycontrast(kappas, quote(E/H))
