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

In jbryer/multilevelPSA: Multilevel Propensity Score Analysis

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

mlpsa.circ.plot(x, xlab = names(multilevelPSA$level2.summary)[4],
  ylab = names(multilevelPSA$level2.summary)[5], legendlab = "Level 2",
  title = NULL, overall.col = "blue", overall.ci.col = "green",
  level1.plot = FALSE, level1.point.size = NULL, level1.rug.plot = NULL,
  level1.projection.lines = FALSE, level2.plot = TRUE,
  level2.point.size = NULL, level2.rug.plot = "tr",
  level2.projection.lines = TRUE, level2.label = FALSE,
  unweighted.means = FALSE, weighted.means = FALSE, fill.colors = NULL,
  ...)

Arguments

x	the results of mlpsa.
xlab	label for the x-axis.
ylab	label for the y-axis.
legendlab	the label for the legend, or NULL to exclude.
title	title for the figure.
overall.col	the color used for the overall results.
overall.ci.col	the color used for the confidence intervals.
level1.plot	logical value indicating whether level 1 points should be plotted.
level1.point.size	the size of level 1 points
level1.rug.plot	the placement for plotting a level 2 rug. Possible values are bl (for left and bottom), tr (for top and right), or NULL (to exclude).
level1.projection.lines	logical value indicating whether level 1 project lines (parallel to the unit line) are drawn.
level2.plot	logical value indicating whether level 2 points should be plotted.
level2.point.size	the size of level 2 points
level2.rug.plot	the placement for plotting a level 2 rug. Possible values are bl (for left and bottom), tr (for top and right), or NULL (to exclude).
level2.projection.lines	logical value indicating whether level 2 project lines (parallel to the unit line) are drawn.
level2.label	logical value indicating whether level 2 points should be labeled.
unweighted.means	logical value indicating whether horizontal and vertical lines are drawn representing the unweighted (i.e. unadjusted from phase I of PSA) means for each level 2, or cluster.
weighted.means	logical value indicating whether horizontal and vertical lines are drawn representing the weighted means for each level 2, or cluster.
fill.colors	if specified, the colors to use for level 2 points.
...	currently unused.
