Description Usage Arguments Details Value Author(s) See Also

This function allows the user to plot a saved hypothesis test object, including normal curves, critical values, shading, and p-values. It requires the HH package and the normal.and.t.dist function written by Dr. Richard Heiberger. Please note that a much better version of this function is currently under development.

`x`	an `htest` object that is the result of a hypothesis test.
`hypoth.or.conf`	a switch to choose between plots for hypothesis tests or confidence intervals
`...`	further arguments to be passed to or from other methods.

This is a plot method for hypothesis tests or confidence intervals which uses the normal.and.t.dist function in the HH package.
