%- Also NEED an '\alias' for EACH other topic documented here.
\title{ Plot various distributions then interactivly adjust the parameters. }
\description{
Plot a curve of a distribution, then using a Tk slider window adjust
the parameters and see how the distribution changes. Optionally also
plots reference distributions.
}
\usage{
vis.binom()
vis.gamma()
vis.normal()
vis.t()
}
%- maybe also 'usage' for other objects documented here.
\details{
These functions plot a distribution, then create a Tk slider box that
allows you to adjust the parameters of the distribution to see how the
curve changes.
Check boxes are available in some cases to also show reference
distributions (normal and poisson for the binomial, exponential and
chi-squared for gamma, and normal for t). The exponential and
chi-squared distributions are those with the same mean as the plotted
gamma.
If you change the plotting
ranges then you need to click on the 'refresh' button to update the plot.
}
\value{
These functions are run for their side effects and do not return
anything meaningful.
