plot.triangle.matches: Triangle plot drawing matched triplets.

In TriMatch: Propensity Score Matching of Non-Binary Treatments

Description

This plot function adds a layer to plot.triangle.psa drawing matched triplets. If p is supplied, this function will simply draw on top of the pre-existing plot, otherwise plot.triangle.psa will be called first.

Usage

## S3 method for class 'triangle.matches'
plot(x, sample = 0.05,
  rows = sample(nrow(tmatch), nrow(tmatch) * sample), line.color = "black",
  line.alpha = 0.5, point.color = "black", point.size = 3, p, ...)

Arguments

x	matched triplets from link{triangle.match}.
sample	an number between 0 and 1 representing the percentage of matched triplets to draw.
rows	an integer vector corresponding to the rows in tmatch to draw.
line.color	the line color.
line.alpha	the alpha for the lines.
point.color	color of matched triplet points.
point.size	point size for matched triplets.
p	a ggplot to add the match lines. If NULL, then plot.triangle.psa.
...	other parameters passed to plot.triangle.psa.

Details

If this function calls plot.triangle.psa, it will only draw line segments and points for those data rows that were used in the matching procedure. That is, data elements not matched will be excluded from the figure. To plot all segments and points regardless if used in matching, set p = plot(tpsa).

Value

a ggplot2 graphic.
