Hello,
My R package **cxhull** is based on the C library **Qhull**. Not only it can compute the vertices of a convex hull, it also returns the edges of the convex hull, and more.
I need the edges of the convex hull of a set of 240 8-dimensional points. Using my package results in a crash of the laptop (not enough RAM, perhaps).
So is there a package in Julia that can help me? Note that it should not triangulate the convex hull, otherwise there will be some edges which are not edges of the convex hull.

A search of [JuliaHub](https://juliahub.com/ui/Search) reveals a few candidates.

I found nothing. I finally got my edges with the Python library **pycddlib**. I opened an issue on **CDDLib.jl** and the author has added this feature now. I have to test it.
