Convex hulls after nMDS or PCoA

Dear all. I need to build convex hulls around groups of points of an
ordination (nMDS or PCoA). The groups were independently established with
cluster analysis. I have learnt to plot convex hulls but would need to
create every of the 21 groups independently. Do you know how could I just
add the hulls to the ordination plot in an easier way?
Thank you very much,
Fernando.

Hi,

I use a modified version of dbscan::hullplot() but https://rseek.org
turns up a bunch of possibilities.
