amvee R Documentation
Fast Approximate Minimum Volume Enclosing Ellipsoid
Description
Given a set of current x/y positions, this function computes an
approximation of their minimum volume enclosing ellipsoid.
Usage
amvee(x)
Arguments
x
A matrix with two columns corresponding to the x and y positions for
which to compute the ellipsoid.
Value
A vector with 5 elements: the x and y coordinated of the center of
the ellipsoid, the width and height of the ellipsoid, and the angle of the
ellipsoid relative to the y axis.

Examples
x <- rnorm(25, 4)
y <- rnorm(25, 2)
ell <- amvee(cbind(x, y))
plot(x, y, asp = 1)
lines(ellipse(ell[1], ell[2], ell[3], ell[4], ell[5]))
