plot.norMix: Plotting Methods for 'norMix' Objects

Description

The plot and lines methods for norMix objects draw the normal mixture density, optionally additonally with a fitted normal density.

Usage

## S3 method for class 'norMix':
plot(x, type = "l", n = 511, xout = NULL, xlim = NULL,
      xlab = "x", ylab = "f(x)", main = attr(x, "name"), lwd = 1.4,
      p.norm = TRUE, p.h0 = TRUE, p.comp = FALSE,
      parNorm = list(col = 2, lty = 2, lwd = 0.4),
      parH0 = list(col = 3, lty = 3, lwd = 0.4),
      parComp = list(col= "blue3", lty = 3, lwd = 0.4), ...)
## S3 method for class 'norMix':
lines(x, type = "l", n = 511, xout = NULL,
      lwd = 1.4, p.norm = FALSE, parNorm = list(col = 2, lty = 2, lwd = 0.4),
      ...)

Arguments

x

object of class norMix.

type

character denoting type of plot, see, e.g. lines.

n

number of points to generate if xout is unspecified.

xout

numeric or NULL giving the abscissae at which to draw the density.

xlim

range of x values to use; particularly important if xout is not specified where xlim is passed to dnorMix and gets a smart default if unspecified.

xlab,ylab

labels for the x and y axis with defaults.

main

main title of plot, defaulting to the norMix name.

lwd

line width for plotting with a non-standard default.

p.norm

logical indicating if the normal density with the same mean and variance should be drawn as well.

p.h0

logical indicating if the line $y = 0$ should be drawn.

p.comp

logical indicating if the Gaussian components should also be drawn individually.

parNorm

graphical parameters for drawing the normal density if p.norm is true.

parH0

graphical parameters for drawing the line $y = 0$ if p.h0 is true.

parComp

graphical parameters for drawing the single components if p.comp is true.

...

further arguments passed to and from methods.
