Boxplot for 'ps' objects

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.method's were used.
color	If 'FALSE', a grayscale figure will be returned.
time	For use with iptw fits.
...	Additional arguments that are passed to boxplot function, which may bepassed to the underlying 'lattice' package plotting functions.
