# S4 method for output_maat
plot(
  x,
  y,
  type,
  examinee_id = 1,
  cut_scores = NULL,
  theta_range = c(-4, 4),
  main = NULL,
  box_color = "PaleTurquoise"
)

Arguments

x

x

y

y

type

the type of plot. route plots the number of examinees routed to each path across the course of entire assessment. correlation produces a scatterplot of thetas across administrations. audit plots interim thetas over modules for a single examinee.

examinee_id

the examinee ID to plot.

cut_scores

(optional) a named list containing cut scores for each grade.

theta_range

the theta range to use in scatter plots when x is an examinee list.

main

the figure title to use in scatter plots when x is an examinee list.

box_color

the cell color to use when type is route. (default = PaleTurquoise)

Value

the route plot.
