This function scrapes articles from the current issue of a specified Nature journal, extracting article titles, URLs, and abstracts with robust fallback handling.
Usage
get_articles(journal, article_selector = ".c-card.c-card--flush",
title_selector = "h3 a", url_selector = "h3 a",
abstract_selector = ".c-card__summary", verbose = FALSE)Arguments
- journal
Character string. The full name of the Nature journal (e.g., "Nature Biotechnology", "Nature Medicine").
- article_selector
Character string. CSS selector for locating articles on the journal's webpage. Default is ".c-card.c-card–flush".
- title_selector
Character string. CSS selector for extracting article titles. Default is "h3 a".
- url_selector
Character string. CSS selector for extracting article URLs. Default is "h3 a".
- abstract_selector
Character string. CSS selector for extracting article abstracts. Default is ".c-card__summary".
- verbose
Logical. If TRUE, prints messages about progress and internal steps. Default is FALSE.
Value
A tibble with columns: title, url, abstract, and source. If no articles are found, returns an empty tibble.
Details
The journal argument is matched (case-insensitively) against available entries from nat_journals().
If not found, an informative error is thrown. Abstracts that are missing are replaced with "Abstract not available".
If titles, URLs, and abstracts differ in length, they are truncated to the shortest length with a warning.
