Read more about the correlation functions in the rstatix package:

cor_test()
cor_mat(), cor_get_pval(), and cor_pmat()
cor_mark_significant() to add significance levels
pull_triangle(), pull_upper_triangle(), and pull_lower_triangle()
cor_reorder() to reorder the matrix
cor_gather() and cor_spread() to reshape the correlation analysis results from matrix to list or vice versa
cor_as_symbols() to only show the symbols (e.g., ., +, *) in the matrix
cor_plot() to visualize the correlation matrix

For many other kinds of correlations (e.g., partial, Bayesian, multilevel, polychoric, biweight, percentage bend, Sheperd's Pi, distance), check out the correlation package.
