ggcircular 0.2.0

ggcircular 0.2.0

Version 0.2.0 adds a conditional visualization workflow for directional
dependence on cylinders and tori.

Highlights

• Circular topography and phase loom layers for circular-linear data.
• Toroidal topography, toroidal flow and conditional ridge layers for
  circular-circular data.
• Cross-validated smoothing selection and marginal-support diagnostics.
• Conditional-ridge diagnostics for multiple local modes and near-tied modes.
• Pointwise bootstrap displays using circular intervals for toroidal ridges.
• Executable README examples and three workflow vignettes for the new displays.

Corrections and validation

• Signed plotting coordinates no longer remove observations above pi before
  toroidal statistics are computed.
• Filled topographies and their isocontours are computed from the same complete
  sample and density estimate.
• The first-grid-maximum ridge selection remains unchanged for compatibility;
  ambiguity is reported separately.
• The package test suite, source build, vignettes, pkgdown site and
  R CMD check --as-cran validation were completed for this release.

Version 0.2.0 and its reproducibility supplement are distributed through the
tagged GitHub release. It is not submitted to CRAN; the CRAN release remains
version 0.1.0.

Reproducibility supplement update

The reproducibility supplement was refreshed on 21 August 2026 to document the
ggalluvial prerequisite for the positioning-table panels, standardize the
marginal-support axis label, retain the complete per-replication simulation
output and tighten the archive manifest. The package tag and tarball are
unchanged.
