Plan and size

Write a field-tagged query, measure how large it is, and partition it into a reproducible plan.

scopus_plan() is_scopus_plan(): Build a reproducible 'Scopus' search plan
scopus_query(): Build a field-tagged 'Scopus' query
scopus_count(): Count 'Scopus' results for a query
scopus_field_tags(): Recognised 'Scopus' field tags

Run a plan against the API, caching each cell so that an interrupted harvest resumes without re-spending quota.

scopus_fetch(): Fetch 'Scopus' records for a query
scopus_fetch_plan(): Execute a 'Scopus' search plan, with optional caching and resume
scopus_abstract(): Retrieve abstracts and richer metadata
scopus_corpus(): Assemble a minimal, cross-tool corpus with keywords and references
scopus_cache_dir(): Managed cache directory for scopusflow
scopus_cache_clear(): Clear the scopusflow managed cache

The retrieved table itself, what it holds, and how to summarise and combine harvests.

as_tibble(<scopus_records>) as.data.frame(<scopus_records>) autoplot(<scopus_records>) scopus_records() is_scopus_records(): Normalise raw 'Scopus' entries to a stable tidy schema
summary(<scopus_records>): Summarise a set of 'Scopus' records
scopus_combine() c(<scopus_records>): Combine record sets into one
scopus_quota(): Parse 'Scopus' quota and rate-limit headers

Extract the identifiers of a harvest, and see what a later retrieval added or dropped.

Summarise a literature over time and by source, compare topics within it, and plot the result.

scopus_trend(): Annual publication counts for a query
scopus_top(): Most frequent values in a record set
scopus_compare_topics(): Compare publication trends across topics
scopus_intersections(): Count a set of concepts and their intersections
plot_scopus_trend() autoplot(<scopus_trend>): Plot a publication trend
plot_scopus_top() autoplot(<scopus_top>): Plot the most frequent values in a record set
plot_scopus_comparison() autoplot(<scopus_comparison>): Plot a topic comparison
plot_scopus_intersections() autoplot(<scopus_intersections>): Plot concept and intersection sizes

Hand records to bibliometrix, to a reference manager, or to a file on disk.

as_bibliometrix(): Convert records to a bibliometrix-compatible data frame
as_bibtex() as_ris(): Export records to BibTeX or RIS
write_scopus_records() read_scopus_records(): Read and write 'Scopus' record sets

The code-free interface to the same workflow.

Check whether a key is configured before making a call that needs one.

The bundled harvest that the examples and the app’s demo mode run on.
