Details

Convert an PubMed-file from PubMed into a data frame. The PubMed-file should contain PubMed-IDs, abstracts from research articles, abstract title, publication year, abstract language, and article type. The data frame created holds at least six columns, namely

  • PMID, containing the PubMed-ID,

  • Year, containing the publication year,

  • Title, containing the title of the abstracts,

  • Abstract, containing the actual abstract,

  • Language, containing the language(s) of the paper,

  • Type, containing the article type.

If topic is provided, a "Topic" column is added, assigning all abstracts in df to topic.

read_pubmed() is faster than read_pubmed_jats() and thus recommended.
