This is a plot of individual weighted residuals (IWRES) 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

iwres.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. Here, the default is c(0,0), specifying a horizontal line at y=0.

smooth

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

...

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

Value

Returns an xyplot of IWRES vs IDV.

Details

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

xpdb <- simpraz.xpdb

iwres.vs.idv(xpdb)


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