LMK_ellipse: Confidence Ellipses

In ehrlichd/lmkCHK: Tools to Visualize and Screen 2D/3D Landmark Data

Description

Draw confidence ellipses around data

Usage

LMK_ellipse(
  dat,
  ci = c(67.5, 90, 95, 99),
  linesCol = "black",
  fillCol = "grey",
  smoothness = 20
)

Arguments

dat	data to be plotted in matrix form [X,Y]
ci	Confidence interval to be plotted. Must be one of c(67.5, 90, 95,99)
linesCol	Color for the line. Currently takes hsv() format
fillCol	color for the fill. Currently only takes hsv() format, set NULL for no fill
smoothness	Smoothness for ellipses. Default should be sufficient but is customizable.

Examples

set.seed(1)

datx <- rnorm(100,0,1)
daty <- rnorm(100,0,10)

dat <- cbind(datx, daty)

plot(dat)
LMK_ellipse(dat, ci = 90)
