# list2ballot: Repeat ith element of list x or row of matrix/data.frames for... In votesys: Voting Systems, Instant-Runoff Voting, Borda Method, Various Condorcet Methods

## Description

Suppose you have 3 different unique ballots and the amount of each ballot is 10, 20, 30. Now you want to create raw ballots as a list. Then you can use this function. See examples for usage.

## Usage

 `1` ```list2ballot(x = NULL, n = rep(1, length(x)), m = NULL, string = NULL) ```

## Arguments

 `x` a list, each element of which should be a vector. Note: only one of `x`, `m` and `string` can be a non-NULL object `n` how many times each element of `x` or each row of `m` should be replicated. It should be a numeric vector of non-negative integers and the length of it should be equal to that of `x` or the row number of `m`. The default is 1 for each element of `x`. `m` a matrix or dataframe, the number of rows should be equal to the length of n. `string` default is NULL. If it is not NULL, `x`, `m` and `n` are ignored. It should be a character vector. Each one contains two parts, the 1st is the amount of that ballot, and the 2nd part contains the names. The 1st and 2nd parts, as well as the names, should be split by spaces or punctuations. But no space and punctuation is allowed inside the names ("_" is not taken to be a punctuation). See examples.

## Value

a list with replicated vectors, if `x` is not NULL, or a matrix/data.frame with duplicated rows, if `m` is not NULL.

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23``` ```# Use x and n unique_ballot <- list( c("A", "B", "C"), c("F", "A", "B"), c("E", "D", "C", "B", "F", "A"), c("x","x", "A") ) r <- c(1, 2, 3, 0) y <- list2ballot(unique_ballot, r) # Use string, x and n will be ignored. # The characters can be written in a very loose way as follows, # for the function will automatically delete unwanted parts. # But do make sure there is no space or punctuation # inside the names. unique_ballot <- c( "2, Bob, Mike Jane", "3: barack_obama;;Bob>Jane", "0 Smith Jane", " 1 Mike???!!!" ) y <- list2ballot(string = unique_ballot) # Use a matrix. m <- matrix(c(1, 2, 3, 3, 1, 2), nrow = 2, byrow = TRUE) colnames(m) <- c("p1", "p2", "p3") r <- c(3, 5) y <- list2ballot(m = m, n = r) ```
