In RDS: Respondent-Driven Sampling

Plots the recruitment network using the Reingold Tilford algorithm.

Description

Plots the recruitment network using the Reingold Tilford algorithm.

Usage

reingold.tilford.plot(
  x,
  vertex.color = NULL,
  vertex.color.scale = hue_pal(),
  vertex.size = 2,
  vertex.size.range = c(1, 5),
  edge.arrow.size = 0,
  vertex.label.cex = 0.2,
  vertex.frame.color = NA,
  vertex.label = get.id(x),
  show.legend = TRUE,
  plot = TRUE,
  ...
)

Arguments

x	An rds.data.frame
vertex.color	The name of the categorical variable in x to color the points with.
vertex.color.scale	The scale to create the color palette.
vertex.size	The size of the vertex points. either a number or the name of a column of x.
vertex.size.range	If vertex.size represents a variable, vertex.size.range is a vector of length 2 representing the minimum and maximum cex for the points.
edge.arrow.size	The size of the arrow from recruiter to recruitee.
vertex.label.cex	The size expansion factor for the vertex.labels.
vertex.frame.color	the color of the outside of the vertex.points.
vertex.label	The name of a variable to use as vertex labels. NA implies no labels.
show.legend	If true and either vertex.color or vertex.size represent variables, legends will be displayed at the bottom of the plot.
plot	Logical, if TRUE then a plot is produced of recruitment tree. ratio statistic with the observed statistics plotted as a vertical dashed line.
...	Additional parameters passed to plot.igraph.

Value

A two-column vector of the positions of the nodes in the recruitment tree.
