The chull function returns the indexes of the points in the input that
form the convex hull. Thus, to test whether or not the convex hull is a
triangle, you simply test to see if its length is 3, i.e.
length(chull(x)) == 3
If you need more information, you'll have to provide a reproducible
example.
