Calculate g-index

Computes the g-index for entities at the specified level. The g-index is the largest g such that the top g works have at least g^2 citations in total (Egghe, 2006).

Usage

sm_metric_g_index(
  corpus,
  level = c("author", "institution", "source", "country"),
  self_corrected = FALSE,
  call = rlang::caller_env()
)

Arguments

corpus

An sm_corpus object.

level

Character; the entity level. Defaults to "author".

self_corrected

Logical (default FALSE); remove self-citations (sm_self_citation()) before computing the index. Author/institution only.

call

Caller environment for error reporting.

Value

A tibble with columns for the entity ID/name and g_index.
