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

 
## S3 method for class 'mnps'
plot(x, plots = "optimize", pairwiseMax = TRUE, figureRows = NULL,  
	color = TRUE, subset = NULL, treatments = NULL, singlePlot = NULL, 
	multiPage = FALSE, time = NULL, print = TRUE, ...)

`x`	An mnps object.
`plots`	An indicator of which type of plot is desired. The options are "optimize" or 1 A plot of the balance criteria as a function of the GBM iteration "boxplot" or 2 Boxplots of the propensity scores for the treatment and control cases "es" or 3 Plots of the standardized effect size of the pre-treatment variables before and after reweighing "t" or 4 Plots of the p-values from t-statistics comparing means of treated and control subjects for pretreatment variables, before and after weighting. "ks" or 5 Plots of the p-values from Kolmogorov-Smirnov statistics comparing distributions of pretreatment variables of treated and control subjects, before and after weighting.
`pairwiseMax`	If `FALSE`, the plots for the underlying `ps` fits will be returned. Otherwise, pairwise maxima will be returned.
`figureRows`	The number of rows of figures that should be used. If left as `NULL`, twang tries to find a reasonable value.
`color`	If `color = FALSE` figures will be gray scale.
`subset`	Used to restrict which of the `stop.method`s will be used in the figure. For example `subset = c(1,3)` would indicate that the first and third `stop.method`s (in alphabetical order of those specified in the original call to `mnps`) should be included in the figure.
`treatments`	Only applicable when `pairwiseMax` is `FALSE` and `plots` 3, 4, and 5. If left at `NULL`, panels for all treatment pairs are created. If one level of the treatment variable is specified, plots comparing that treatment to all others are produced. If two levels are specified, a comparison for that single pair is produced.
`singlePlot`	For plot calls that produce multiple plots, specifying an integer value of `singlePlot` will return only the corresponding plot. E.g., specifying `singlePlot = 2` will return the second plot.
`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.
`print`	If FALSE, the figure is returned but not printed.
`...`	Additional arguments.

This function produces lattice-style graphics of diagnostic plots.
