wres.vs.cov: Weighted residuals (WRES) plotted against covariates, for...

Description Usage Arguments Details Value Author(s) See Also Examples

Description

This creates a stack of plots of weighted residuals (WRES) plotted against covariates, and is a specific function in Xpose 4. It is a wrapper encapsulating arguments to the xpose.plot.default and xpose.plot.histogram functions. Most of the options take their default values from xpose.data object but may be overridden by supplying them as arguments.

Usage

1
2
wres.vs.cov(object, ylb = "WRES", smooth = TRUE, type = "p",
  main = "Default", ...)

Arguments

object

An xpose.data object.

ylb

A string giving the label for the y-axis. NULL if none.

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.

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 over-plotted 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.

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.

...

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

Details

Weighted residuals (WRES) are plotted against each covariate present, as specified in [email protected]@Xvardef$covariates, creating a stack of plots.

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

Value

Returns a stack of xyplots and histograms of CWRES versus covariates.
