Source: R/similarities.R
fractional_approach.Rd

Matrix transformation from incidence matrices to citation networks, fractional counting for co-citation or fractional counting for bibliographic coupling

Usage

fractional_approach(
  A1,
  A2,
  approach = c("citation", "cocitation", "bcoupling")
)

Arguments

A1

From incidence matrix (e.g. paper and authors)

A2

To incidence matrix (e.g. author to paper)

approach

Character string, “citation”, “cocitation” and “bcoupling”

Value

Return a type of "citation network"
