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,
      parNorm = list(col = 2, lty = 2, lwd = 0.4),
      parH0 = list(col = 3, 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.

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.

...

further arguments passed to and from methods.
