(Internal) Plot audit trail of a single examinee

Description

plotShadowAudit is an internal function for plotting audit trail of a single examinee, showing interim theta estimates over the course of an adaptive test.

Usage

plotShadowAudit(x, theta_range, z_ci, use_par, ...)

Arguments

x	an output_Shadow object.
theta_range	the theta range to use on the y-axis.
z_ci	the confindence interval value to use in the z metric. z_ci = 1.96 is equivalent to plotting 95% error bars.
use_par	TRUE allows this function to set graphic margins through par.
...	not used.
