You can either give draw_rs() an declaration, as created by `declare_rs`

or you can specify the other arguments to describe a random sampling procedure.

draw_rs(declaration = NULL, N = NULL, strata = strata_var, clusters = clust_var, n = NULL, prob = NULL, strata_n = NULL, strata_prob = NULL, simple = FALSE, strata_var = NULL, clust_var = NULL)

declaration | A random sampling declaration, created by |
---|---|

N | The number of units. N must be a positive integer. (required) |

strata | A vector of length N that indicates which stratum each unit belongs to. |

clusters | A vector of length N that indicates which cluster each unit belongs to. |

n | Use for a design in which n units (or clusters) are sampled. In a stratified design, exactly n units in each stratum will be sampled. (optional) |

prob | Use for a design in which either floor(N*prob) or ceiling(N*prob) units (or clusters) are sampled. The probability of being sampled is exactly prob because with probability 1-prob, floor(N*prob) units (or clusters) will be sampled and with probability prob, ceiling(N*prob) units (or clusters) will be sampled. prob must be a real number between 0 and 1 inclusive. (optional) |

strata_n | Use for a design in which strata_n describes the number of units to sample within each stratum. |

strata_prob | Use for a design in which strata_prob describes the probability of being sampled within each stratum. Differs from prob in that the probability of being sampled can vary across strata. |

simple | logical, defaults to FALSE. If TRUE, simple random sampling is used. When simple = TRUE, please do not specify n or strata_n. |
