Detect scholarly identifier types

Source: R/detect_scholid_type.R
detect_scholid_type.Rd

Performs best-effort detection of scholarly identifier types from possibly wrapped identifier strings (e.g., URLs or labels).

For each element of the input, the function returns the first matching identifier type, or NA_character_ if no supported type matches.

Detection first attempts classification based on canonical identifier syntax (see classify_scholid()). If no match is found, the function attempts per-type normalization (see normalize_scholid()) and returns the first type for which normalization yields a non-missing result.

Use normalize_scholid() to convert detected values to canonical form once the identifier type is known.

Usage

detect_scholid_type(x)

Arguments

x

A vector of candidate identifier values.

Value

A character vector of the same length as x, giving the detected identifier type for each element, or NA_character_ if no match is found.
