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.
# S3 method for 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, ...)matched triplets from link{triangle.match}.
an number between 0 and 1 representing the percentage of matched triplets to draw.
an integer vector corresponding to the rows in tmatch to draw.
the line color.
the alpha for the lines.
color of matched triplet points.
point size for matched triplets.
a ggplot to add the match lines. If NULL, then plot.triangle.psa.
other parameters passed to plot.triangle.psa.
a ggplot2 graphic.
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).
