I have made a minor update to v0.55.0. This will likely be a new accepted version on CRAN; so you can (in a day or 2) install in R simply by "install.packages('brainGraph')". It is also available via Github, as usual.
I added a function, "plot_rich_norm", that simplifies plotting the rich-club coefficient curves. For all changes, please see the "NEWS.md" file (highlighted in green) at
the Github diff page.
I have also updated the User Guide to reflect these minor changes.
