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.

Returns

A data frame containing R the labelled B matrix.

myBMatrix <- sysToBMatrixDf(ConQuestSys())
## Not run:

# if you run the above example you will have the B Matrix from the example system file.
str(myBMatrix)
