dfs() deprecated arguments

Code
  d <- dfs(g, root = 2, unreachable = FALSE, neimode = "out", father = TRUE)
Condition
  Error:
  ! The `neimode` argument of `dfs()` was deprecated in igraph 1.3.0 and is now defunct.
  i Please use the `mode` argument instead.

bfs() works

Code
  g <- graph_from_literal(a - +b - +c, z - +a, d)
  bfs(g, root = 2, mode = "out", unreachable = FALSE, order = TRUE, rank = TRUE,
    parent = TRUE, pred = TRUE, succ = TRUE, dist = TRUE)
Output
  $root
  [1] 2

  $mode
  [1] "out"

  $order
  + 2/5 vertices, named:
  [1] b c

  $rank

  $parent

laplacian_matrix() works

Code
  laplacian_matrix(Ai, normalization = "unnormalized")
Output
  3 x 3 sparse Matrix of class "dgCMatrix"

  [1,]  410 -210 -200
  [2,] -210  590 -380
  [3,] -200 -380  580
