ppplot.das: PP plot

Description

This function computes a PP (Probability-Probability) plot for the given dataset.

Usage

        lwd = 2, pch = 3, cex = 0.7, cex.lab = 1, ...)

Value

No return value, creates a plot.

Arguments

x

dataset

pdist

the distribution function

xlab, ylab, lwd, pch, cex, cex.lab

graphical parameters

line

if a regression line should be added

...

further parameters for the probability function
