Plot Rank Membership Profile (RMP) from exametrika

This function takes exametrika output as input and generates Rank Membership Profile (RMP) plots using ggplot2. RMP shows each student's membership probability across all latent ranks.

Usage

plotRMP_gg(
  data,
  title = TRUE,
  colors = NULL,
  linetype = "dashed",
  show_legend = FALSE,
  legend_position = "right"
)

Arguments

data: An object of class c("exametrika", "LRA"), c("exametrika", "Biclustering"), c("exametrika", "LDLRA"), or c("exametrika", "LDB"). If LCA or BINET output is provided, CMP will be plotted instead with a warning.
title: Logical or character. If TRUE (default), display an auto-generated title. If FALSE, no title. If a character string, use it as a custom title (only for single-student plots).
colors: Character vector. Color(s) for points and lines. If NULL (default), a colorblind-friendly palette is used.
linetype: Character or numeric specifying the line type. 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".

Value

A list of ggplot objects, one for each student. Each plot shows the membership probability across all latent ranks.

Details

The Rank Membership Profile visualizes how strongly each student belongs to each latent rank. Unlike class membership, rank membership has an ordinal interpretation. Students with unimodal profiles centered on a single rank are well-classified.

Examples

library(exametrika)
# \donttest{
result <- LRA(J15S500, nrank = 5)
plots <- plotRMP_gg(result)
plots[[1]] # Show RMP for the first student

# }
