In dga: Capture-Recapture Estimation using Bayesian Model Averaging

Description

A helper function.

Usage

remove.close.ellipse(ps, x, y, a, b, alpha)

Arguments

ps	an n x 2 matrix of potential points.
x	the x coordinate of the center of the ellipse.
y	the y coordinate of the center of the ellipse.
a	the x-radius of the ellipse.
b	the y-radius of the ellipse.
alpha	the angle of rotation of the ellipse.

Value

inds	a vector of length nrow(ps) that tells whether each row of ps is near the border of the ellipse defined by x,y,a,b, and alpha.
