lead() / lag() give meaningful errors

Code
  lead(letters, -1)
Error <rlang_error>
  `n` must be a nonnegative integer scalar, not a double vector of length 1.

Code
  lead(letters, "1")
Error <rlang_error>
  `n` must be a nonnegative integer scalar, not a character vector of length 1.

Code
  lag(letters, -1)
Error <rlang_error>
  `n` must be a nonnegative integer scalar, not a double vector of length 1.

Code
  lag(letters, "1")
Error <rlang_error>
  `n` must be a nonnegative integer scalar, not a character vector of length 1.

Code
  lag(ts(1:10))
Error <rlang_error>
  `x` must be a vector, not a ts object, do you want `stats::lag()`?

Code
  lag(c("1", "2", "3"), default = FALSE)
Error <vctrs_error_incompatible_type>
  Can't combine `default` <logical> and `x` <character>.

Code
  lag(c("1", "2", "3"), default = character())
Error <rlang_error>
  `default` must be size 1, not size 0
