`authority_score()` works

Code
  s3 <- authority_score(g2, options = arpack_defaults)$vector
Condition
  Warning:
  `authority_score()` was deprecated in igraph 2.1.0.
  i Please use `hits_scores()` instead.
  Warning:
  arpack_defaults was deprecated in igraph 1.6.0.
  i Please use `arpack_defaults()` instead.
  i So the function arpack_defaults(), not an object called arpack_defaults.

`hub_score()` works

Code
  s3 <- hub_score(g2, options = arpack_defaults)$vector
Condition
  Warning:
  `hub_score()` was deprecated in igraph 2.0.3.
  i Please use `hits_scores()` instead.
  Warning:
  arpack_defaults was deprecated in igraph 1.6.0.
  i Please use `arpack_defaults()` instead.
  i So the function arpack_defaults(), not an object called arpack_defaults.

eigen_centrality() deprecated scale argument

Code
  eigen_centrality(g, scale = TRUE)
Condition
  Warning:
  The `scale` argument of `eigen_centrality()` is deprecated as of igraph 2.1.1.
  i eigen_centrality() will always behave as if scale=TRUE were used.
