Shared worker for plotLCD_gg / plotLRD_gg — .plot_student

The two exported functions draw the same student-distribution plot; they differ only in which model family is the "native" one (class vs rank) and therefore in which direction the redirect warning fires.

Usage

.plot_student_distribution(
  data,
  Num_Students,
  title,
  colors,
  linetype,
  show_legend,
  legend_position,
  prefer
)

Arguments

data: An object of class c("exametrika", "LCA") or c("exametrika", "BINET"). If LRA or Biclustering output is provided, LRD will be plotted instead with a warning.
Num_Students: Logical. If TRUE (default), display the number of students on each bar.
title: Logical or character. If TRUE (default), display the auto-generated title. If FALSE, no title. If a character string, use it as a custom title.
colors: Character vector of length 2. First element is the bar fill color, second is the line/point color. If NULL (default), uses gray for bars and black for line/points.
linetype: Character or numeric specifying the line type for the frequency line. Default is "dashed".
show_legend: Logical. If TRUE, display the legend. Default is FALSE.
legend_position: Character. Position of the legend. One of "right" (default), "top", "bottom", "left", "none".
prefer: Either "class" (plotLCD_gg) or "rank" (plotLRD_gg).

Value

A ggplot object.
