cograph 1.5.2

Breaking Changes

• Standardized first parameter name to x across all plotting functions:
  • plot_tna(): input → x
  • plot_htna(): input → x (was model)
  • plot_mtna(): input → x (was model)
  • splot() already used x

Bug Fixes

• Fixed tplot() default margins causing tiny plots compared to splot()

Documentation

• Added qgraph to splot migration guide (vignettes/qgraph-to-splot.Rmd)
• Added multi-group, multi-cluster, and multilevel networks vignette (vignettes/multi_network.Rmd)

cograph 1.5.1

Breaking Changes (with backwards compatibility)

The following parameters have been renamed for consistency. The old names still work but emit deprecation warnings:

Improvements

• edge_label_fontface now accepts string values (“plain”, “bold”, “italic”, “bold.italic”) in addition to numeric values, matching other fontface parameters
• Added deprecation helper infrastructure for backwards-compatible parameter renaming
• Standardized all public API parameters to use consistent snake_case naming

cograph 1.4.0

New Features

• Added mlna() for multilevel network visualization with 3D perspective
• Added mtna() for multi-cluster network visualization
• Added plot_htna() for hierarchical multi-group polygon network layouts with circular layout option
• Added tplot() as qgraph drop-in replacement
• Added arrow_angle parameter for customizable arrowheads

Bug Fixes

• Fixed Rd cross-reference warning in splot documentation
• Fixed pie/donut segment divider lines when border width is 0

cograph 1.3.1

New Features

• Added edge_start_dot_density parameter for TNA-style dotted edges
• Added direct support for tna objects via from_tna()
• Added direct support for statnet network and qgraph objects
• Added auto-conversion of pie_values vector to donut_fill when values are in [0,1]
• Removed underscore prefix requirement for custom SVG shapes

Bug Fixes

• Fixed TNA defaults being overwritten in splot()
• Fixed self-loop edge labels and adjusted dotted pattern spacing
• Fixed donut_shape validation error with custom SVG shapes
• Fixed title clipping issue
• Fixed edge rendering crash
• Fixed R CMD check errors and warnings

Improvements

• Added strict vectorization for node/edge label and donut parameters
• Added edge_scale_mode validation
• Improved roxygen documentation
• Added TNA plotting defaults and improved dotted edge style

cograph 1.2.7

Bug Fixes

• Fixed oversized nodes in from_qgraph() with layout override
• Fixed oval layout: use uniform scaling in normalize_coords()
• Fixed edge label alignment issues in from_qgraph()
• Fixed nrow(el) crash: qgraph Edgelist is a list, not data.frame
• Fixed misaligned edge labels by reordering per-edge vectors
• Fixed oval layout node distortion and donut fill for from_qgraph()

Improvements

• Dropped qgraph cut-based edge_color/edge_width and cut param

cograph 1.2.6

New Features

• Added donut_empty parameter
• Added from_qgraph() function for qgraph compatibility

Bug Fixes

• Fixed oval layout_info guard
• Fixed curvature extraction to only pass scalar values

Improvements

• Scaled down edge width, label size, and arrow size from qgraph values
• Improved curvature, threshold/minimum, donut ratio, and node size defaults
• Rewrote from_qgraph() to read resolved graphAttributes

cograph 1.2.0

New Features

• Added soplot() qgraph-compatible plotting function
• Added layout_oval() function for oval/ellipse layouts
• Added layout_scale parameter to expand/contract network layout
• Added layout_scale = "auto" for node-count based scaling
• Added Gephi Fruchterman-Reingold layout algorithm
• Added edge_start_style parameter for direction indication
• Added start segment styling to edge drawing functions

Bug Fixes

• Fixed soplot curving and edge defaults to match splot behavior
• Fixed rescale_layout to use uniform scaling, preserving oval aspect ratio
• Fixed edge scaling producing abnormally thick edges
• Fixed invalid par(pin) error on exit

Improvements

• Added unified parameter scaling for splot/soplot alignment
• Synced all splot() parameters to soplot() for full feature parity

cograph 1.1.0

New Features

• Added splot() function for base R graphics network plotting
• Added polygon donuts, AI shapes, and SVG support
• Added shadow labels and text control options
• Added double donut nodes with separate border controls
• Added edge CI underlays and template-based edge labels
• Added comprehensive legend support for groups, edge colors, and node sizes
• Added high resolution output support
• Added edge curves mode and label styling options
• Added bidirectional arrows, loop rotation, and curve controls

Bug Fixes

• Fixed donut rendering bug and simplified donut_color API
• Fixed arrow positioning and curve direction for qgraph-style edges
• Fixed edge label positioning to avoid overlap with edge lines
• Fixed inward curve direction for splot edges
• Fixed self-loop rendering with qgraph-style circular arcs
• Fixed arrow placement on non-square viewports
• Fixed reciprocal edge auto-separation

Improvements

• Unified splot() and soplot() argument syntax with snake_case
