hullMesh {cxhull}  R Documentation 
Extract the vertices and the faces from a 3d convex hull.
hullMesh(hull, simplify = TRUE, rgl = FALSE)
hull 
a 3d convex hull, output of 
simplify 
Boolean, whether to return the faces as a matrix instead
of a list if possible, i.e. if all faces have the same number of edges;
this argument is possibly ignored if 
rgl 
Boolean, whether to return a rgl mesh (class

A list giving the vertices and the faces, or a rgl mesh.
Unless all faces are triangular, the output does not define a mesh with coherently oriented faces.
