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.
