plot.disc: Plot a discrete distribution function

In nspmix: Nonparametric and Semiparametric Mixture Estimation

Plot a discrete distribution function

Description

Class disc is used to represent an arbitrary univariate discrete distribution with a finite number of support points.

Function disc creates an object of class disc, given the support points and probability values at these points.

Function plot.disc plots the discrete distribution.

Usage

## S3 method for class 'disc'
plot(
  x,
  type = c("pdf", "cdf"),
  add = FALSE,
  col = 4,
  lwd = 1,
  ylim,
  xlab = "",
  ylab = "Probability",
  ...
)

Arguments

x	an object of class disc.
type	plot its pdf or cdf.
add	add the plot or not.
col	colour to be used.
lwd, ylim, xlab, ylab	graphical parameters.
...	arguments passed on to function plot.
