Make Best and Worst Responses from Best-Worst Pair Indices

Source: R/wrapper_mdu.R
make_bw_from_ydif.Rd

Converts a matrix of Best-Worst pair indices (`Y_dif`) into separate `Best` and `Worst` data frames. The returned values are positions within each row of `sets`, not the item labels stored in `sets`.

Usage

make_bw_from_ydif(Y_dif, sets)

restore_bw_from_ydif(Y_dif, sets)

Arguments

Y_dif

Matrix or data frame of pair indices (N persons x P tasks). Each value must be an integer from 1 to `C * (C - 1)`, where `C` is the number of items per task.

sets

Matrix or data frame of presented item sets (P tasks x C items).

Value

A list with two data frames: `Best` and `Worst`.
