An R package to fit unidimensional IRT models and use the results for reviewing items, linking tests and item selection. The package is designed so that it is possible to fit and explore IRT models with a very small number of commands in R. Results of analyses can be viewed using a selection of shiny apps.
Much of the functionality in this package is built upon the existing R package mirt (Chalmers, 2012; https://cran.r-project.org/web/packages/mirt/index.html).
