## Inclusion Probabilities: Complete Random Sampling

### Description

Inclusion Probabilities: Complete Random Sampling

### Usage

    complete_rs_probabilities(N, n = NULL, n_unit = NULL, prob = NULL,
      prob_unit = NULL, check_inputs = TRUE)

### Arguments

`N` | The number of units. N must be a positive integer. (required)
`n` | Use for a design in which exactly n units are sampled. (optional)
`n_unit` | unique(n_unit) will be passed to `n`. Must be the same for all units (optional)
`prob` | Use for a design in which either floor(N*prob) or ceiling(N*prob) units are sampled. The probability of being sampled is exactly prob because with probability 1-prob, floor(N*prob) units will be sampled and with probability prob, ceiling(N*prob) units will be sampled. prob must be a real number between 0 and 1 inclusive. (optional)
`prob_unit` | unique(prob_unit) will be passed to the prob argument and must be the same for all units.
`check_inputs` | logical. Defaults to TRUE.

### Value

A vector length N indicating the probability of being sampled.

### Examples

    probs <- complete_rs_probabilities(N = 100)
    table(probs)

    probs <- complete_rs_probabilities(N = 100, n = 50)
    table(probs)

    probs <- complete_rs_probabilities(N=100, prob = .3)
    table(probs)
