Include key article information when DOI is missing — update_article

This function appends pretty_article_label to include the journal and we use this information to fill in any entry where the DOI is missing. (Note: DOIs were introduced in the late 1990s and so articles from before this time often do not have one.)

Usage

update_article_info(articles)

Arguments

articles: A data frame containing information about the articles. This will typically be the output of load_epidata_raw.

Value

A modified data frame with an updated column "doi" with NA values replaced with either (1) article_label appended to include journal where available or (2) just article_label when journal entry is NA.

Examples

articles <- data.frame(
  doi = c("10.123", NA, "10.234"),
  article_label = c("Smith 2020", "Smith 1979", "Smith 2023"),
  journal = c("Science", "Nature", "The Lancet")
)
