.TL
?qqplot: Probability Plot for Arbitrary Distribution
.CS
?qqplot(x, dist,par1,par2)
.PP
.AG x
Data to be plotted.
.AG dist
Name of distribution (e.g., t, beta, chisq) Default is
?PROMPT(What distribution?).
.AG pari
Optionally, parameters to the distribution.  (Note that
location and scale parameters are not needed; only shape or
degrees of freedom).
.SH EFFECT
Produces a probability (Q-Q) plot from an arbitrary distribution,
so long as there is a corresponding quantile function.
.EX
?qqplot( rnorm(50), t, 3) #random normals vs t on 3 d.f.
