Read an R object of class ConQuestSys and create a labelled
representation of the B matrix (scoring matrix). This maps item response
categories to items and dimensions. Returns long data frame, where items are
duplicated if they are in many dimensions.
Usage
sysToBMatrixDf(mySys, applyLabels = TRUE)
Value
A data frame containing R the labelled B matrix.
Arguments
mySys
An R object of class ConQuestSys,
returned by the function conquestr::ConQuestSys
applyLabels
A bool indicating whether labels
(e.g., dimension labels) should be appended.
myBMatrix <- sysToBMatrixDf(ConQuestSys())
if (FALSE) {
# if you run the above example you will have the B Matrix from the example system file.str(myBMatrix)
}
