boxplot.ps: Boxplots for ps objects

In twang: Toolkit for Weighting and Analysis of Nonequivalent Groups

Description

This function produces a collection of diagnostic plots for ps objects.

Usage

 
## S3 method for class 'ps'
boxplot(x, subset=NULL, color = TRUE, time = NULL, ...)

Arguments

x	A ps object
subset	If multiple stop.method rules were used in the ps() call, subset restricts the plots of a subset of the stopping rules that were employed. This argument expects a subset of the integers from 1 to k, if k stop.methods were used.
color	If set to FALSE, grayscale figures will be produced
time	Used to specify a subset of times for use with the iptw function. Ignored for standard ps fits.
...	Additional arguments that may be passed to the underlying lattice package plotting functions

Details

This function produces lattice-style graphics of diagnostic plots.
