Area of the alpha-convex hull

Description

This function calculates the area of the α-convex hull of a sample of points.

Usage

areaahull(x, timeout = 5)

Arguments

x	Object of class "ahull".
timeout	A numeric specifying the maximum number of seconds the expression is allowed to run before being interrupted by the timeout.

Value

area	Area of the α-convex hull. If the area cannot be computed, the output will be NA with a warning.

Examples

## Not run: 
# Random sample in the unit square
x <- matrix(runif(500), nc = 2)
# Value of alpha
alpha <- 1
# alpha-convex hull
ahull.obj <- ahull(x, alpha = alpha)
# Area of the alpha-convex hull
areaahull(ahull.obj)

## End(Not run)
