ppplot.das: PP plot

In StatDA: Statistical Analysis for Environmental Data

PP plot

Description

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

Usage

ppplot.das(x, pdist = pnorm, xlab = NULL, ylab = "Probability", line = TRUE, 
        lwd = 2, pch = 3, cex = 0.7, cex.lab = 1, ...)

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

Details

The empirical probability is calculated and compared with the comparison distribution.

Value

No return value, creates a plot.
