plot_tna: TNA-Style Network Plot (qgraph Compatible)

In cograph: Analysis and Visualization of Complex Networks

TNA-Style Network Plot (qgraph Compatible)

Description

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 = COGRAPH_SCALE$tna_edge_color,
  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 = COGRAPH_SCALE$tna_edge_color,
  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().

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)

## Not run: 
m <- matrix(runif(25), 5, 5)
tplot(m)

## End(Not run)
