siberConvexhull {SIBER} | R Documentation |
Calculate metrics and plotting information for convex hulls
Description
This function calculates the area of the convex hull describing a set of bivariate points, and returns other information useful for plotting the hull.
Usage
siberConvexhull(x, y)
Arguments
x |
a vector of x-axis data |
y |
a vector of y-axis data |
Value
A list of length four comprising:
-
TA
the area of the convex hull. -
hullX
the x-coordinates of the points describing the convex hull. -
hullY
the y-coordinates of the points describing the convex hull. -
ind
the indices of the original data inx
andy
that form the boundaries of the convex hull.
Examples
x <- stats::rnorm(15)
y <- stats::rnorm(15)
