Computes the concave hull for a set of points (wrapper for concaveman::concaveman)
concave_hull(points, concavity = 1, length_threshold = 0)
A data frame of points.
A value that determines the concavity (1 = detailed shape, Inf = convex hull).
Segment lengths less than this threshold are not considered; higher values give simpler shapes.
# NOT RUN { concave_hull() # }
