Plots densities and ranges for the propensity scores.

Usage

# S3 method for class 'psrange'
plot(
  x,
  xlab = NULL,
  ylab = NULL,
  labels = c("Comparison", "Treatment"),
  text.ratio.size = 4,
  text.ncontrol.size = 3,
  point.size = 1,
  point.alpha = 0.6,
  line.width = 6,
  density.alpha = 0.2,
  rect.color = "green",
  rect.alpha = 0.2,
  ...
)

Arguments

x: the result of psrange.
xlab: label for x-axis.
ylab: label for y-axis.
labels: labels for the comparison and treatment legend.
text.ratio.size: size of the text for the ratio.
text.ncontrol.size: size of the text for the number of control units.
point.size: size of the points for the minimum and maximum ranges for each model.
point.alpha: the alpha (transparency) level for the points.
line.width: the width of the line between the median of the minimum and maximum ranges.
density.alpha: the alpha (transparency) level of the density curves.
rect.color: the color of the rectangle surrounding the range of minimum and maximum ranges.
rect.alpha: the alpha (transparency) level of the rectangle.
...: currently unused.
