abstract: Extend Rasch and Item Response Theory (IRT) analyses by providing tools
  for post-processing the output from five major IRT packages (i.e., 'eRm', 'psychotools',
  'ltm', 'mirt', and 'TAM'). The current version provides the plotPIccc() function,
  which extracts from the return object of the originating package all information
  required to draw an extended Person-Item-Map (PIccc), showing any combination of
  * category characteristic curves (CCCs), * threshold characteristic curves (TCCs),
  * item characteristic curves (ICCs), * category information functions (CIFs), *
  item information functions (IIFs), * test information function (TIF), and the *
  standard error curve (S.E.). for uni- and multidimensional models (as far as supported
  by each package). It allows for selecting dimensions, items, and categories to plot
  and offers numerous options to adapt the output. The return object contains all
  calculated values for further processing.
