xpose4 (version 4.5.0)

parm.vs.cov: Parameters plotted against covariates, for Xpose 4

Description

This creates a stack of plots of Bayesian parameter estimates plotted against covariates, and is 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

parm.vs.cov(object,
           onlyfirst=TRUE,
           smooth=TRUE,
           type="p",
           main="Default",
           ...)

Arguments

object

An xpose.data object.

onlyfirst

Logical value indicating whether only the first row per individual is included in the plot.

smooth

Logical value indicating whether an x-y smooth should be superimposed. The default is TRUE.

type

The plot type - defaults to points only.

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 <

...

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

Value

• Returns a stack of xyplots and histograms of parameters against covariates.

Details

Each of the parameters in the Xpose data object, as specified in object@Prefs@Xvardef$parms, is plotted against each covariate present, as specified in object@Prefs@Xvardef$covariates, creating a stack of plots.

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