plotCqHist

generates a plot from a history object. Use <code>getCqHist</code> to create a history object from an 'ACER ConQuest' system file.

Extends 'ACER ConQuest' through a family of functions
designed to improve graphical outputs and help with advanced analysis
(e.g., differential item functioning). Allows R users to call
'ACER ConQuest' from within R and read 'ACER ConQuest' System Files
(generated by the command `put` <https://conquestmanual.acer.org/s4-00.html#put>).
Requires 'ACER ConQuest' version 5.29.5 or later.
A demonstration version can be downloaded from <https://shop.acer.org/acer-conquest-5.html>.

plotCqHist function

<dl><dt>myHist</dt>
<dd>an R object created by the <code>getCqHist</code> function.</dd>
<dt>centre</dt>
<dd>a Boolean representing whether the iteration history should be mean centred (within parameter).
This is helpful for plots that include all parameters to ensure the Y axis is sensible. Consider a plot with raw values of the Likelihood and item parameters on it.</dd>
<dt>params</dt>
<dd>A vector of which params to plot. Must be one or more of "all", "Likelihood", "Beta", Variance", "Xsi", "Tau".</dd>
<dt>legend</dt>
<dd>Should a legend be plotted?.</dd></dl>
