Triangle plot drawing matched triplets.

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 [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()].

Value

a `ggplot2` graphic.

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)`.
