I am having some problems with svydesign() in R. My sample design is a 2 stage stratification.

ie.design=svydesign(id=~1,strata=~a+b,fpc=~fpc1+fpc2,data=x)

How should my fpc2 term be constructed? I having tried including the population size within each strata. i.e.

    library(survey)
    library(dplyr)

    new2=x %>% group_by(a,b) %>% summarise(Freq=n())

    x=merge(x, new2, by=c("a","b"))

    design=svydesign(id=~1,strata=~a+b,fpc=~fpc1+fpc2,data=x)

    Error in popsize < sampsize : non-conformable arrays
