netrics 0.2.0

Package

• Added roxygen2 parameter templates (param_attr, param_data, param_dir, param_memb, param_motf, param_norm, param_select) and net/node/tie-level templates (net_measure, net_motif, node_mark, node_measure, node_member, node_motif, tie_mark, tie_measure) for consistent function documentation.
• Fixed startup messages.

Measuring

• Renamed node_adoption_time() to node_by_adopt_time()
• Renamed node_thresholds() to node_by_adopt_threshold()
• Renamed node_exposure() to node_by_adopt_exposure()
  
• Renamed node_recovery() to node_by_adopt_recovery()
  
• Separated centralisation scripts into different files per measure type (betweenness, closeness, degree, eigenvector) for easier maintenance, and into different documentation per level (node, tie) for better organization.
• Updated and separated brokerage, diversity/assortativity, cohesion, closure, cliques, components, features, and hierarchy documentation by level.

Members

• Separated node_in_community() documentation from the hierarchical and non-hierarchical community-detection algorithms.
• Core documentation split into separate mark, measure, and member pages.
• Improved various functions that rely on a membership argument to accept both a membership vector and a string identifier of a network attribute.

Motifs

• Renamed net_by_change() to net_x_change() and related functions to reflect their motif (subgraph-counting) nature.

Methods

• Added gap method for cluster k-selection in method_k().
• Renamed model_k() to method_k() and related cluster-selection utilities renamed for clarity.

netrics 0.1.0

Release notes

{netrics} 0.1.0 is the first formal release of the package as a standalone analytic engine for the stocnet ecosystem. The analytic functions — marks, measures, motifs, and memberships — have been extracted from {manynet} and {migraph} into this dedicated package, with consistent naming conventions and a range of bug fixes.

New naming conventions

All functions now follow a consistent verb–object–qualifier naming scheme:

• Marks (node_is_*(), tie_is_*()): logical vectors identifying which nodes or ties hold a particular structural property.
• Measures (*_by_*()): numeric vectors at the network (net_by_*()), node (node_by_*()), or tie (tie_by_*()) level.
• Motifs (*_x_*()): tabular counts of nodes’ or networks’ participation in structural sub-patterns.
• Memberships (*_in_*()): categorical vectors assigning nodes to groups (components, communities, equivalence classes, etc.).

Functions previously named with other prefixes (e.g. node_centrality_*, net_cohesion_*, node_equivalency_*) have been renamed to follow the *_by_*() / *_x_*() / *_in_*() convention. tie_by_cohesion() now correctly returns a tie_measure class object.

• node_by_randomwalk() now works with two-mode networks.
• net_by_degree(), net_by_harmonic(), and net_by_reach() now consistently include the function call in the returned object.
