smoothUnchull: smoothUnchull

In sajuukLyu/ggunchull: A ggplot extension for drawing smooth non-convex irregular circles around a set of points.

smoothUnchull

Description

Get a hull of input set of points. The hull can be non-convex.

Usage

smoothUnchull(x, y, nbin = 100, nsm = 10, addsm = 1, qval = 0.95, sfac = 1.5)

Arguments

x	a vector of x coordinates
y	a vector of y coordinates
nbin	number of points used to shape the hull, default 100
nsm	number of points used to perform convolution, should less than nbin, default 10
addsm	number of additional times of convolution performed, default 1
qval	quantile of each sector, used to determine the edge of the hull, should less than 1, default 0.95
sfac	expansion size factor, larger value means bigger hull, default 1.5

Value

a list of coordinates of the hull
