cograph 1.5.2

Breaking Changes

Bug Fixes

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:

Old Name New Name Reason
esize edge_size Add edge_ prefix, expand abbreviation
cut edge_cutoff Add edge_ prefix, clarify meaning
usePCH use_pch Fix camelCase to snake_case
positive_color edge_positive_color Add edge_ prefix (matches theme storage)
negative_color edge_negative_color Add edge_ prefix (matches theme storage)
donut_border_lty donut_line_type Expand lty abbreviation

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

Bug Fixes

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

  • 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

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 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

cograph 1.2.0

New Features

  • Added soplot() qgraph-compatible plotting function
