abstract: A powerful yet simple graphical tool available in the field of psychometrics
  is the Wright Map (also known as item maps or item-person maps), which presents
  the location of both respondents and items on the same scale. Wright Maps are commonly
  used to present the results of dichotomous or polytomous item response models. The
  'WrightMap' package provides functions to create these plots from item parameters
  and person estimates stored as R objects. Although the package can be used in conjunction
  with any software used to estimate the IRT model (e.g. 'TAM', 'mirt', 'eRm' or 'IRToys'
  in 'R', or 'Stata', 'Mplus', etc.), 'WrightMap' features special integration with
  'ConQuest' to facilitate reading and plotting its output directly.The 'wrightMap'
  function creates Wright Maps based on person estimates and item parameters produced
  by an item response analysis. The 'CQmodel' function reads output files created
  using 'ConQuest' software and creates a set of data frames for easy data manipulation,
  bundled in a 'CQmodel' object. The 'wrightMap' function can take a 'CQmodel' object
  as input or it can be used to create Wright Maps directly from data frames of person
  and item parameters.
