IntegrateDesignAndData: 'IntegrateDesignAndData'
In erikerhardt/flipMaxDiff: MaxDiff Experimental Design and Analysis

A matrix where in each row, the first element is the 'best' choice and the last element is the 'worst' choice.

1 2	IntegrateDesignAndData(design, version, best, worst, seed, questions.left.out = 0)

`design`	A `data.frame`, where the first variable is called 'Version', the second is called 'Question', and the remaining variables contain the alternatives shown in each question.
`version`	A vector of integers showing the version of the design shown to each respondent.
`best`	Amatrix of integers showing the choices made by each respondent on each of the questions. One column for each task. The integers need to correspond to the `design` vector of integers showing the version of the design shown to each respondent. Coerced to a matrix if a `data.frame`.
`worst`	As with 'best', except denoting worst..
`seed`	Seed for cross validation
`questions.left.out`	Number of questions to leave out for cross-validation.
