xpose4 (version 4.5.0)

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

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 <

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)
