reQ: Forced Q-Sort Distribution

Description

Replace the values in x with the distribution of values defined by dist.

Usage

reQ(x, dist, ties = "random")

Arguments

x

A data.frame, matrix, or numeric vector containing the values to be reQ'd. It is assumed that the rows are to be reQ'd if a matrix or data.frame is given.

dist

A numeric vector whose sum must be equal to the length of x. The Q values are assumed to be from 1 to length(dist). The values in dist indicate the number of times each Q value is to be used.

ties

A character element passed to the rank function indicating how ties should be broken.

Value

Returns a vector of size x containing data that has been normalized to fit a Q-Sort Distributions

Details

This function takes a vector of data and "normalizes" it by forcing it to fit a Q-sort distributon (see Block, 1978 for information on the Q-sort method).
