R: Plot the prior, likelihood, and posterior on the same plot.
decomp
R Documentation
Plot the prior, likelihood, and posterior on the same plot.
Description
This function takes any object of class Bolstad and plots the prior,
likelihood and posterior on the same plot. The aim is to show the influence
of the prior, and the likelihood on the posterior.
Usage
decomp(x, ...)
Arguments
x
an object of class Bolstad.
...
any other arguments to be passed to the plot function.
Note
Note that xlab, ylab, main, axes,
xlim, ylim and type are all used in the function so
specifying them is unlikely to have any effect.

Examples
# an example with a binomial sampling situation
results = binobp(4, 12, 3, 3, plot = FALSE)
decomp(results)
# an example with normal data
y = c(2.99,5.56,2.83,3.47)
results = normnp(y, 3, 2, 1, plot = FALSE)
decomp(results)
