[R] convex-polygon in scatter plot

I am trying to draw a convex-polygon (envelope) connecting the outer points (of a particular class) in a scatter plot

[which I want to do to illustrate the range of a particular type of samples in an ordination plot].

Is there any function to plot this kind of polygon?

Kind regards
