In dplyr: A Grammar of Data Manipulation

na_rm is validated

Code
  nth(1, 1, na_rm = 1)
Condition
  Error in `nth()`:
  ! `na_rm` must be `TRUE` or `FALSE`, not the number 1.

Code
  nth(1, 1, na_rm = c(TRUE, FALSE))
Condition
  Error in `nth()`:
  ! `na_rm` must be `TRUE` or `FALSE`, not a logical vector.

default must be size 1 (when not used with lists)

Code
  nth(1L, n = 2L, default = 1:2)
Condition
  Error in `nth()`:
  ! `default` must have size 1, not size 2.

default is cast to the type of x (when not used with lists)

Code
  nth("x", 2, default = 2)
Condition
  Error in `nth()`:
  ! Can't convert `default` <double> to match type of `x` <character>.

n is validated (#5466)

Code
  nth(1:10, n = "x")
Condition
  Error in `nth()`:
  ! Can't convert `n` <character> to <integer>.

Code
  nth(1:10, n = 1:2)
Condition
  Error in `nth()`:
  ! `n` must have size 1, not size 2.

Code
  nth(1:10, n = NA_integer_)
Condition
  Error in `nth()`:
  ! `n` can't be `NA`.

x must be a vector

Code
  nth(environment(), 1L)
Condition
  Error in `vec_size()`:
  ! `x` must be a vector, not an environment.

order_by must be the same size as x

Code
  nth(1:5, n = 1L, order_by = 1:2)
Condition
  Error in `nth()`:
  ! `order_by` must have size 5, not size 2.

Code
  nth(1:5, n = 6L, order_by = 1:2)
Condition
  Error in `nth()`:
  ! `order_by` must have size 5, not size 2.
