Flatten a JSON array

json_flatten(
  x,
  ptype = NULL,
  allow_scalars = FALSE,
  wrap_scalars = FALSE,
  bigint_as_char = bigint_default()
)

`x`	A JSON vector.
`ptype`	Output type. If `NULL`, the default, the output type is determined by computing the common type across all elements. Use `new_json_array()` resp. `new_json_object()` if you know every element is an array resp. object. Mind that the return type will only be `json2`.
`allow_scalars`	Do not error for scalar elements?
`wrap_scalars`	Should scalar values be wrapped? Note that scalars are only wrapped if either `ptype` is `new_json_array()` or `json2` vector. `ptype` is `NULL` and the elements are a mix of scalar values and arrays.
`bigint_as_char`	Convert big integers to character? The option `jsontools.bigint_as_char` is used as default.

A flattened version of x with class given by ptype and length equal to the sum of the json_array_length() of the components of x.

json_unnest_longer(), json_unnest_wider()

json_flatten(c("[1, 2]", "[3]"))

# names are kep
json_flatten(c(x = "[1, 2]", y = "[3]"))

# scalar elements produce an error ...
try(json_flatten(c(x = "[1, 2]", y = "3")))
# ... but can be explicitly allowed with `allow_scalars`
json_flatten(c(x = "[1, 2]", y = "3"), allow_scalars = TRUE)
