[en] Differential item functioning (DIF) is an important issue of interest in psychometrics and
educational measurement. Several methods have been proposed in the last decades to identify
items that function differently between two (or more) groups of examinees. Starting from a
framework for classifying DIF detection methods and from a comparative overview of the
most traditional methods, an R package for nine methods, called difR, is presented. The
commands and options are briefly described, and the package is illustrated through the
analysis of a data set on verbal aggression.
