Check to see if a vector is categorical (character or string)

check_categorical(
  x,
  any.missing = TRUE,
  all.missing = TRUE,
  len = NULL,
  min.len = NULL,
  max.len = NULL,
  ...
)

assert_categorical(
  x,
  any.missing = TRUE,
  all.missing = TRUE,
  len = NULL,
  min.len = NULL,
  max.len = NULL,
  ...,
  .var.name = vname(x),
  add = NULL
)

test_categorical(x, ...)

Arguments

x	a vector of things
any.missing	are vectors with missing values allowed? Default is `TRUE`
all.missing	are vectors with missing values allowed? Default is `TRUE`
len	expected length of `x`. If provided, overrides `min.len` and `max.len`. Defaults to `NULL`.
min.len	minimum length for `x`
max.len	maximum length for `x`
...	dots
