xpose4 (version 4.5.3)

cwres.vs.idv: Population conditional weighted residuals (CWRES) plotted against the independent variable (IDV) for Xpose 4

Description

This is a plot of population conditional weighted residuals (CWRES) vs the independent variable (IDV), a specific function in Xpose 4. It is a wrapper encapsulating arguments to the xpose.plot.default function. Most of the options take their default values from xpose.data object but may be overridden by supplying them as arguments.

Usage

cwres.vs.idv(object,
           abline=c(0,0),
           smooth=TRUE,
           ...)

Arguments

object

An xpose.data object.

abline

Vector of arguments to the panel.abline function. No abline is drawn if NULL.

smooth

A NULL value indicates that no superposed line should be added to the graph. If TRUE then a smooth of the data will be superimposed.

…

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

Value

Returns an xyplot of CWRES vs IDV.

Details

Conditional weighted residuals (CWRES) are plotted against the independent variable, as specified in object@Prefs@Xvardef$idv.

Conditional weighted residuals (CWRES) require some extra steps to calculate. See compute.cwres for details.

A wide array of extra options controlling xyplots are available. See xpose.plot.default and xpose.panel.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
cwres.vs.idv(xpdb)

## A conditioning plot
cwres.vs.idv(xpdb, by="HCTZ")

## Logarithmic Y-axis
cwres.vs.idv(xpdb, logy=TRUE)

## Custom colours and symbols, IDs labels
cwres.vs.idv(xpdb, cex=0.6, pch=3, col=1, ids=TRUE)
