TNA-Style Network Plot (qgraph Compatible)

A drop-in replacement for qgraph::qgraph() that uses cograph's splot engine. Accepts qgraph parameter names for seamless migration from qgraph to cograph.

Usage

plot_tna(
  x,
  color = NULL,
  labels = NULL,
  layout = "oval",
  theme = "colorblind",
  mar = c(0.1, 0.1, 0.1, 0.1),
  cut = NULL,
  edge.labels = TRUE,
  edge.label.position = 0.7,
  edge.label.cex = 0.6,
  edge.color = "#003355",
  vsize = 7,
  pie = NULL,
  pieColor = NULL,
  lty = NULL,
  directed = NULL,
  minimum = NULL,
  posCol = NULL,
  negCol = NULL,
  arrowAngle = NULL,
  title = NULL,
  ...
)

tplot(
  x,
  color = NULL,
  labels = NULL,
  layout = "oval",
  theme = "colorblind",
  mar = c(0.1, 0.1, 0.1, 0.1),
  cut = NULL,
  edge.labels = TRUE,
  edge.label.position = 0.7,
  edge.label.cex = 0.6,
  edge.color = "#003355",
  vsize = 7,
  pie = NULL,
  pieColor = NULL,
  lty = NULL,
  directed = NULL,
  minimum = NULL,
  posCol = NULL,
  negCol = NULL,
  arrowAngle = NULL,
  title = NULL,
  ...
)

Arguments

x: A weight matrix (adjacency matrix) or tna object
color: Node fill colors
labels: Node labels
layout: Layout: "circle", "spring", "oval", or a coordinate matrix
theme: Plot theme ("colorblind", "gray", etc.)
mar: Plot margins (numeric vector of length 4)
cut: Edge emphasis threshold
edge.labels: Show edge weight labels
edge.label.position: Position of edge labels along edge (0-1)
edge.label.cex: Edge label size multiplier
edge.color: Edge colors
vsize: Node size
pie: Pie/donut fill values (e.g., initial probabilities)
pieColor: Pie/donut segment colors
lty: Line type for edges (1=solid, 2=dashed, 3=dotted)
directed: Logical, is the graph directed?
minimum: Minimum edge weight to display
posCol: Color for positive edges
negCol: Color for negative edges
arrowAngle: Arrow head angle in radians. Default pi/6 (30 degrees).
title: Plot title
...: Additional arguments passed to splot()

Value

Invisibly returns the cograph_network object from splot().

Examples

# Simple usage
m <- matrix(runif(25), 5, 5)
plot_tna(m)


# With qgraph-style parameters
plot_tna(m, vsize = 15, edge.label.cex = 2, layout = "circle")


# With custom colors
plot_tna(m, color = rainbow(5), vsize = 10)
