abstract: The deltaPlotR package implements Angoff's Delta Plot method to detect dichotomous
  DIF. Several detection thresholds are included, either from multivariate normality
  assumption or by prior determination. Item purification is supported (Magis and
  Facon (2014) <https://doi.org/10.18637/jss.v059.c01>).
