v1.0.3

[jhollway]

Measures

• Fixed two node_by_homophily() issues
  • It was reading a vector attribute against the wrong nodes
  • It was reporting the E-I index where it computed Geary's C
• Fixed net_by_homophily() discarding tie weights before Geary's C
  • Geary's C now declares that on a weighted network, it can exceed 2
• Fixed net_by_spatial() erroring on a two-mode network
  • For one-mode attributes, projection is used
  • For multimodal attributes, the multilevel matrix is read instead
• Fixed net_by_spatial() propogating missing values
• Fixed net_by_diversity() and node_by_diversity() erroring on a factor attribute

Memberships

• Fixed two node_in_leiden() issues
  • It was returning a community for every node on an unweighted network
  • It was overriding a user's resolution
• Fixed node_in_community(), node_in_spinglass() and node_in_fluid()
  treating a weakly connected directed network as unconnected
• Fixed node_in_partition() returning a split it had already improved upon
  • Added start= for a random rather than a node-order initialisation

🟢 Approval recommended

The changes are well-covered by new/updated tests and only a minor release-note typo remains.

Pull request overview

Updates netrics to v1.0.3 with targeted correctness fixes across heterogeneity measures (homophily/spatial/diversity) and community membership algorithms, aligning computation, metadata, and documentation with intended behavior.

Changes:

• Fixes Moran’s I (net_by_spatial()) for two-mode networks (projection vs multilevel), missing attributes, and zero-variance/empty-edge cases.
• Fixes homophily (net_by_homophily(), node_by_homophily()) to correctly handle Geary’s C (including weighted ties) and attribute handling within ego subgraphs.
• Fixes/extends community memberships: node_in_partition() stability (best-pass retention) + new start= option; Leiden default resolution=NULL (density-based) and weak-connectivity eligibility for algorithms that treat graphs as undirected.
