v2.3.4

[jhollway]

Making

• Fixed a couple of generate_islands() errors
  • Fixed to grow bridges as choose(islands, 2) and not as islands
  • Fixed deriving p from a two-mode network with a one-mode dyad count
• Added two-mode support to the last three generate_*() functions (closes Add generate_fire(c(2,2)) and generate_citations(c(2,2))? #150)
  • generate_fire() burns along two-paths, closing four-cycles instead of triangles
  • generate_islands() builds a bipartite blockmodel with a planted diagonal
  • generate_citations() keeps its recency mechanism, but the target crosses the mode divide,
    and both modes grow so that the concentration turns over

Manipulating

• Fixed bind_changes.igraph() replacing the changelog instead of appending
• Added remaining row-wise verbs for the globals component (closes Do we need add_changes, join_changes, or filter_globals? #149)
  • Added bind_globals()
  • Added filter_globals()
  • Added arrange_globals()
  • Added delete_globals()
  • Added mutate_globals() to alter table columns
• Improved to_time() to scope globals as it already scoped ties, changes, and missings

Modifying

• Added to_positive() to shortcut keeping just the positive ties of a signed network (closes Should manynet export a positive-ties guard for downstream packages? #176)

Marking

• Fixed is_signed() to check for a 'sign' column or a negative 'weight' column

🟡 Changes recommended

generate_islands()’s p inference for two-mode inputs still subtracts a one-mode-style bridge-tie count, which can significantly mis-estimate p for islands >= 4.

Pull request overview

This PR prepares the manynet 2.3.4 release by extending stochastic generators to support two-mode networks, introducing a to_positive() helper for signed networks, and tightening signed-network detection for edgelists.

Changes:

• Added two-mode implementations for generate_fire(), generate_islands(), and generate_citations(), with updated documentation and tests.
• Added to_positive() as an exported guard that keeps only positive ties for signed networks, plus tests and documentation.
• Fixed is_signed.data.frame() to detect signedness via a sign column or negative weight values (instead of relying on column position).
