Retrieves full text (JATS XML where available) from Europe PMC or bioRxiv, for
feeding into extract_krt(). Returns NULL offline or when the text is not
openly available.
Usage
fetch_fulltext(id, source = c("auto", "europepmc", "biorxiv"), timeout = 30)
Arguments
- id
A PMCID, DOI, or bioRxiv DOI.
- source
"auto", "europepmc", or "biorxiv".
- timeout
Request timeout in seconds.
Value
A character string of the full text or abstract, or NULL.
Examples
# \donttest{
# Contacts Europe PMC. Offline, or when the text is not openly available,
# this returns NULL rather than failing.
txt <- fetch_fulltext("PMC5334499")
is.null(txt) || nchar(txt) > 0
#> [1] TRUE
# }
