Changes in version 0.4.4 (2026-05-20) CRAN pre-test fix - The four test-equiv-*.R equivalence suites (vs bibliometrix and biblionetwork) have been moved out of the package into a local-only local_testing_and_equivalence/ directory. These developer checks pulled in data.table/biblionetwork, whose OpenMP parallelism caused the "CPU time 4 times elapsed time" NOTE on the Debian r-devel pre-test. They remain runnable locally but are no longer part of R CMD check. - bibliometrix, biblionetwork, and data.table removed from Suggests — they were used only by the relocated equivalence tests. - tests/testthat.R keeps a 2-thread BLAS/OpenMP cap as defence for crossprod() / tcrossprod() in multiply_bipartite(). - No user-facing code changes. Changes in version 0.4.3 CRAN reviewer requests - All no-run wrappers in reader examples replaced with runnable examples, per CRAN reviewer guidance. File-based readers (read_scopus, read_wos, read_dimensions, read_lens) now use small bundled fixtures under inst/extdata/, reached via system.file(). API-wrapper readers (read_openalex, read_crossref) use an inline data frame matching the upstream column shape so the conversion path runs without a network call. read_biblio examples now demonstrate multi-file, directory, and generic-CSV modes against the bundled fixtures. - New fixtures: inst/extdata/scopus_sample.csv, wos_sample.txt, dimensions_sample.csv, lens_sample.csv (2 records each). Changes in version 0.4.2 Documentation - Title renamed to "Importing, Constructing, and Exporting Bibliometric Networks" to reflect the full lifecycle scope. - Description rewritten to lead with attention-weighted networks (lead, last, proximity, circular) and other differentiators (position-aware counting, similarity/dissimilarity normalisations, temporal windows, disparity-filter backbone, historiograph, local citation scoring), dropping the enumeration of standard co-network types. - README intro re-leads with capabilities; numerical method counts removed. - Internal-comment author attributions stripped throughout. Changes in version 0.4.1 Bug fixes - read_lens() no longer inflates output to n^2 rows when neither Lens ID nor ID columns are present. - read_openalex() no longer inflates output to n^2 rows when the id column is absent. - read_scopus() now normalises empty-string DOIs to NA, so is.na(doi) deduplication checks behave as expected. - read_wos() empty-file return now includes the keywords_plus list-column to match the non-empty schema. - read_crossref() no longer crashes with "row names contain missing values" when the issued column has NA entries. Documentation - Converter examples (to_igraph(), to_tbl_graph(), to_cograph()) now use @examplesIf requireNamespace(...) so they execute when the suggested package is installed instead of being silently skipped. - read_biblio(), read_bibtex(), and read_ris() now ship runnable examples backed by either the bundled extdata/openalex_works.csv fixture or a tempfile()-based minimal record. - Reference list streamlined across DESCRIPTION, README, vignette, and Rd files. Testing - Added eight new test files covering read_scopus(), read_wos(), read_ris(), read_lens(), read_dimensions(), read_crossref(), read_biblio(), read_openalex(), plus dedicated coverage for R/edgelist.R and build_bipartite_long(). - Suite size: 1268 tests (was 499). Package line coverage: 92.5% (was 61.8%). Changes in version 0.3.0 New functions - temporal_network() — builds time-windowed networks with fixed, sliding, or cumulative strategies. Results include a window column for easy stacking. - historiograph() — Garfield-style chronological citation network among the most locally cited documents. - local_citations() — counts within-dataset citations (Local Citation Score). - backbone() — disparity filter for extracting statistically significant edges from dense weighted networks. - prune() — threshold and top-n edge pruning. - read_biblio() — universal reader with auto-format detection (Scopus, WoS, BibTeX, RIS, Dimensions, Lens.org). - read_dimensions() — Dimensions CSV export reader. - read_crossref() — converter for rcrossref::cr_works() output. - to_gephi() — exports node and edge tables in Gephi CSV format; writes nodes.csv + edges.csv when a directory path is supplied. - to_graphml() — pure base-R GraphML writer; no XML package required. - to_cograph() — converts edge list to a cograph_network object with optional node metadata for direct use with cograph::splot(). Improvements - All edge list functions now sort output by weight descending and reset row names. - local_citations() canonical column order: id, lcs, gcs, year, title, journal, doi. - historiograph() empty-result schema matches non-empty schema. - All readers share a standard column order: id, title, year, journal, doi, cited_by_count, abstract, type, authors, references, keywords, then source-specific extras. - backbone() and prune() use single-pass O(m) node statistics via tapply() / split() — faster on large networks. - temporal_network() converted from for loop to lapply. - read_dimensions() / read_crossref() now apply standardize_authors() and standardize_refs() for consistency with other readers. Changes in version 0.2.0 Breaking changes - Argument count renamed to counting; measure renamed to similarity across all network functions. - co_network() renamed to conetwork(). New functions - read_openalex() — reads OpenAlex JSON export. - filter_top() — keeps only the top-n most connected nodes. - normalize() — post-hoc normalisation of any edge list. Changes in version 0.1.0 Initial release. - 8 network builders: author_network(), document_network(), reference_network(), keyword_network(), institution_network(), country_network(), source_network(), conetwork(). - 13 counting methods including harmonic, geometric, golden ratio, adaptive geometric. - 6 similarity normalisations: association strength, cosine, Jaccard, inclusion, equivalence. - 6 readers: Scopus, Web of Science, OpenAlex, BibTeX, RIS, Lens.org. - Converters: to_igraph(), to_tbl_graph(), to_matrix(). - Numerically validated against bibliometrix and biblionetwork.
