This function produces a collection of diagnostic plots for mnps objects.
Usage
## S3 method for class 'mnps'
boxplot(x, stop.method = NULL, color = TRUE, figureRows = NULL,
singlePlot = NULL, multiPage = FALSE, time = NULL, print = TRUE, ...)
Arguments
x
A ps object
stop.method
Only 1 stop.method can be presented at a time for mnps objects. Use a numeric indicator of which stop.method (among those specified when fitting the mnps object) should be used.
color
If FALSE, a grayscale figure will be returned.
figureRows
The number of rows in the figure. Defaults to the number of panels.
singlePlot
If multiple sets of boxplots are produced, singlePlot can be used to select only one. For example, singlePlot = 2 would return only the second set of boxplots.
multiPage
When multiple frames of a figure are produced, multiPage = TRUE will print each frame on a different page. This is intended for situations where the graphical output is being saved to a file.
time
For use with iptw fits.
print
If FALSE, the figure is returned but not printed.
...
Additional arguments that may be passed to the underlying lattice package plotting functions
Details
This function produces lattice-style graphics of diagnostic plots.
