xpose4 (version 4.5.3)

addit.gof: Additional goodness-of-fit plots, for Xpose 4

Description

This is a compound plot consisting of plots of weighted population residuals (WRES) vs population predictions (PRED), absolute individual weighted residuals (|IWRES|) vs independent variable (IDV), WRES vs IDV, and weighted population residuals vs log(IDV), a specific function in Xpose 4. It is a wrapper encapsulating arguments to the wres.vs.pred, iwres.vs.idv and wres.vs.idv functions.

Usage

addit.gof(object,
           type="p",
           title.size=0.02,
           title.just=c("center","top"),
           main="Default",
           force.wres=FALSE,
           ...)

Arguments

object

An xpose.data object.

type

1-character string giving the type of plot desired. The following values are possible, for details, see 'plot': '"p"' for points, '"l"' for lines, '"o"' for overplotted points and lines, '"b"', '"c"') for (empty if '"c"') points joined by lines, '"s"' and '"S"' for stair steps and '"h"' for histogram-like vertical lines. Finally, '"n"' does not produce any points or lines.

title.size

Amount, in a range of 0-1, of how much space the title should take up in the plot)

title.just

how the title should be justified

main

The title of the plot. If "Default" then a default title is plotted. Otherwise the value should be a string like "my title" or NULL for no plot title. For "Default" the function xpose.multiple.plot.title is used.

force.wres

Plot the WRES even if other residuals are available.

…

Other arguments passed to link{xpose.plot.default}.

Value

Returns a compound plot comprising plots of weighted population residuals (WRES) vs population predictions (PRED), absolute individual weighted residuals (|IWRES|) vs independent variable (IDV), WRES vs IDV, and weighted population residuals vs log(IDV).

Details

Four additional goodness-of-fit plots are presented side by side for comparison.

A wide array of extra options controlling xyplots are available. See xpose.plot.default and xpose.multiple.plot.default for details.

Examples

## We expect to find the required NONMEM run and table files for run
## 5 in the current working directory
xpdb5 <- xpose.data(5)


## Here we load the example xpose database 
data(simpraz.xpdb)
xpdb <- simpraz.xpdb

## A vanilla plot
addit.gof(xpdb)

## Custom colours and symbols
addit.gof(xpdb, cex=0.3, pch=0, col=8)
