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:
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
