epm_query_by_fulltitle: Query PubMed by Full-length Title.

Description

Execute a PubMed query using a full-length publication title as query string. Tokenization and stopword removal is automatically performed. The goal is to mimic a Pubmed citation matching search. Because of this approach, it is possible that a query by full-length title may return more than one record.

Usage

epm_query_by_fulltitle(
  fulltitle,
  field = "[Title]",
  api_key = NULL,
  verbose = TRUE
)

Value

an easyPubMed object.

Arguments

fulltitle

String (character vector of length 1) that corresponds to the full-length publication title used for querying PubMed (titles should be used as is, without adding trailing filter tags).

field

String (character vector of length 1). This indicates the PubMed record field where the full-length string (fulltitle) should be searched in. By default, this points to the 'Title' field. However, the field can be changed (always use fields supported by PubMed) as required by the user (for example, to attempt an exact-match query using a specific sentence included in the abstract of a record).

api_key

String (character vector of length 1), corresponding to the NCBI API key. Can be `NULL`.

verbose

Logical, shall details about the progress of the operation be printed to console.
