plot.NpdeObject: Plots a NpdeObject object

In npde: Normalised Prediction Distribution Errors for Nonlinear Mixed-Effect Models

Plots a NpdeObject object

Description

Plots the data and diagnostic plots in a NpdeObject object

Usage

## S3 method for class 'NpdeObject'
plot(x, y, ...)

Arguments

x	a NpdeObject object
y	unused, here for compatibility with the base plot function
...	additional graphical parameters, which when given will supersede graphical preferences stored in the object

Details

The default plots are represented as a 2x2 array with distribution plots on the top row (histogram and QQ-plot), and scatterplots of npde versus independent variable and population predictions on the bottom row. The graph is plotted in a graphic device window, unless the result is stored in an object (eg myplot<-plot(x)) which can then be printed (eg using print(myplot)).
