A (too long in the making) new version of WrightMap is now available on CRAN (Actually, version 1.2.1 is already up).

This new version includes a lot of features that have long been requested, including cut-point lines, alternative item displays (classical Wright Map look, histogram view), and differential item functioning plots among others.

We have updated the package tutorials on our website to reflect the changes to this version, and we will be publishing additional posts showing the new features.

We hope these changes can be of use to you, and we look forward to hearing your feedback!

Change log for this version:

Major changes:

wrightMap split into data handling and plotting, each of which is further split into person & item side. The data handling functions are further split by filetype and the plotting functions are split by plot types. For data handling, this is meant to make it possible to have item and person data of different filetypes. For plotting, this is meant to make the plotting function more flexible and make it easier to add different plot styles. Details:
