plot.mlpsa: Plots the results of a multilevel propensity score model.

In multilevelPSA: Multilevel Propensity Score Analysis

Plots the results of a multilevel propensity score model.

Description

The plot created uses the ggplot2 framework. As such, additional modifications can be made. This plot is an extension of the circ.psa function in the PSAgraphics package for multilevel models.

Usage

## S3 method for class 'mlpsa'
plot(x, ratio = c(1, 2), plotExtra = NULL, ...)

Arguments

x	the results of [mlspa()].
ratio	the ratio of the size of the distribution plots (left and bottom) to the circular plot.
plotExtra	a plot to place in the lower left corner.
...	parameters passed to [mlpsa.circ.plot()] and [mlpsa.distribution.plot()]

Examples

## Not run: 
require(multilevelPSA)
require(party)
data(pisana)
data(pisa.colnames)
data(pisa.psa.cols)
mlctree = mlpsa.ctree(pisana[,c('CNT','PUBPRIV',pisa.psa.cols)], formula=PUBPRIV ~ ., level2='CNT')
student.party = getStrata(mlctree, pisana, level2='CNT')
student.party$mathscore = apply(student.party[,paste0('PV', 1:5, 'MATH')], 1, sum) / 5
results.psa.math = mlpsa(response=student.party$mathscore, 
       treatment=student.party$PUBPRIV, 
       strata=student.party$strata, 
       level2=student.party$CNT, minN=5)
