CHANGES IN conquestr VERSION 1.5.5

NEW FEATURES

• Added support for ACER ConQuest system files version 30 which are created by the command put (https://conquestmanual.acer.org/s4-00.html#put) in ACER ConQuest Version > 5.47.

CHANGES IN conquestr VERSION 1.5.0

NEW FEATURES

• Added support for ACER ConQuest system files version 29 which are created by the command put (https://conquestmanual.acer.org/s4-00.html#put) in ACER ConQuest Version > 5.42.

MAJOR CHANGES

• conquestr::getCqItan now returns estimated scores in the item tables rather than raw scores. Previous versions would the pre-key value and the raw score associated with the pre-key value (these two values are identical when no key or recode is used). The values are now the pre-key value and the estimated score. In the case of models without estimated scores (e.g., Rasch models) the raw score is the same as the estimated score.

CHANGES IN conquestr VERSION 1.4.4

NEW FEATURES

• Added support reading uncompressed system files in markdown and shiny workflows previously, the function that worked out if a system file was compressed threw an invisible error that would break, for example, knitr workflows.
• Added support for polytomies and scores in genItems.
• added support for itanals that include groups.

MAJOR CHANGES

• conquesrt::getCqItan now returns a list of list of lists. The top level list is the return object. Each element of this list is a group from the itanal. In most use cases this is “all cases” and the length of this list is 1. Therefore, to get the 4th item analysis table for the first group is now accessed by returnObject[[1]][[4]] instead of returnObject[[4]]
