If plot_option is "profile", then only a bar plot of item response probabilities. If plot_option is "tree", then only a plot of the tree structure.

Examples

data(result_diet_1000iters)
burnin <- 500
summarized_result <- summary(result_diet_1000iters, burnin, relabel = TRUE, be_quiet = TRUE)
plot(x = summarized_result, item_name_list = NULL, plot_option = "all")
