Assert that an input is a vector/list with desired properties

Description

Assert that an input is a vector/list with desired properties

Usage

assert_vector(
  x,
  class,
  len = NULL,
  null_ok = FALSE,
  var_name = NULL,
  subset_of = NULL,
  named = FALSE,
  n_call = -1L
)

assert_list(x, len = NULL, null_ok = FALSE, named = FALSE)

assert_class(x, class, n_call = -1)

Arguments

`x`	A vector/list. The input to be analysed.
`class`	A string. The class that this input should inherit from.
`len`	An integer. The length of the vector. If `NULL`, length is not checked.
`null_ok`	A logical. Whether the input could also be `NULL`.
`var_name`	A string. The name of the variable in the informative message. If `NULL`, the name is guessed from the function call.
`subset_of`	A character vector. If `x` is a character vector, specifies which values it can take. If `NULL`, values are not checked.
`named`	A logical. Whether the input should be a named vector/list. If `FALSE` this check is not enforced (i.e. the input object can be named even if named is `FALSE`).
`n_call`	A negative integer. The number of frames to go back to find the call to associate the error generated by the function with. Defaults to the parent frame (-1). This argument is only relevant to other assertion functions that build on top of this one.
