# make.sample: make.sample and friends In elec: Collection of functions for statistical election audits

## Description

These methods are for SIMULATION STUDIES. These functions will build a sample, i.e. simulated, record of votes given certain parameters.

## Usage

 ```1 2 3 4 5 6 7``` ```make.cartoon(n = 400, vote.dist = c(125, 113, 13), stratify = TRUE) make.sample(M, N, strata = 1, per.winner = NULL, worst.e.max = NULL, R = NULL, tot.votes = 1e+05) make.sample.from.totals(vote.W, vote.L, totals) make.sample.from.totals.margin(M, totals, per.winner = NULL) ```

## Arguments

 `M` The margin desired between the winner and loser (as a percent). `N` Number of precincts desired. `strata` Number of strata desired. `per.winner` The percent of votes the winner should receive. `worst.e.max` The worst e.max possible for any precinct. `R` The "dispersion" a measure of how unequal in size precincts should be. R needs to be greater than 0. NULL indicates equal size. For R between 0 and 1, the precincts are distributed 'linearly', i.e., the size of precinct i is proportional to i. At 2, the smallest precint will be near 0 and the largest twice the average votes per precinct. After 2, the precincts are distributed in a more curved fashion so that the smaller precincts do not go negative. `tot.votes` The total votes desired. `vote.W` Total votes for winner. `vote.L` Total votes for loser. `totals` Vector of total votes for precincts. `vote.dist` reported votes for C1, C2, and C3 in order for all precincts.prompt `n` Size of sample. `stratify` Should the sample be stratified?

## Details

make.cartoon() makes the sample scenario described in Stark's CAST paper.

## Value

A elec.data object meeting the desired specifications.
