lag() gives informative error for objects

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

lead() / lag() validate n

Code
  lead(1:5, n = 1:2)
Condition
  Error in `lead()`:
  ! `n` must be a whole number, not an integer vector.
Code
  lead(1:5, -1)
Condition
  Error in `lead()`:
  ! `n` must be positive.

Code
  lag(1:5, n = 1:2)
Condition
  Error in `lag()`:
  ! `n` must be a whole number, not an integer vector.
Code
  lag(1:5, -1)
Condition
  Error in `lag()`:
  ! `n` must be positive.

lead() / lag() check for empty dots

Code
  lead(1:5, deault = 1)
Condition
  Error in `lead()`:
  ! `...` must be empty.
  x Problematic argument:
  * deault = 1

Code
  lag(1:5, deault = 1)
Condition
  Error in `lag()`:
  ! `...` must be empty.
  x Problematic argument:
  * deault = 1

lead() / lag() require that x is a vector

Code
  lead(environment())
Condition
  Error in `lead()`:
  ! `x` must be a vector, not an environment.

Code
  lag(environment())
Condition
  Error in `lag()`:
  ! `x` must be a vector, not an environment.

default must be size 1 (#5641)

Code
  shift(1:5, default = 1:2)
Condition
  Error in `shift()`:
  ! could not find function "shift"

Code
  shift(1:5, default = integer())
Condition
  Error in `shift()`:
  ! could not find function "shift"

n is validated

Code
  shift(1, n = 1:2)
Condition
  Error in `shift()`:
  ! could not find function "shift"

order_by must be the same size as x

Code
  shift(1:5, order_by = 1:4)
Condition
  Error in `shift()`:
  ! could not find function "shift"
