recommendations for passing extra arguments through `...` in `lapply() `and al.

[ThomasSoeiro]

Should the style guide provide recommendations for passing extra arguments through ... in lapply() and al.? In particular, should the extra arguments be named when passed to a function with no default arguments?

E.g. with function signature f(x, y):

# bad?
lapply(1:3, f, 4)

# good?
lapply(1:3, f, y = 4)

[ThomasSoeiro]

lintr::lint("lapply(1:3, f, 4)\n") (version 2.0.1) does not complain and Advanced R mentions:

add <- function(x, y) x + y
lapply(list(1:3, 4:5), add, 3)

Suggesting that maybe "good" and "bad" are respectively:

# good?
lapply(1:3, f, 4)

# bad?
lapply(1:3, f, y = 4)
