Create Arrow arrays

Usage

narrow_array_data(
  buffers = NULL,
  length = 0,
  null_count = -1,
  offset = 0,
  children = NULL,
  dictionary = NULL
)

narrow_array_data_info(x, ...)

as_narrow_array_data(x, ...)

# S3 method for narrow_array_data
as_narrow_array_data(x, ...)

as_narrow_buffer(x, ...)

# S3 method for default
as_narrow_buffer(x, ...)

Arguments

buffers: A list() of R vectors whose memory serves as an underlying buffer in the Arrow format.
length: The logical size of the array
null_count: The number of NULL values or -1 if this hasn't been computed yet.
offset: The number of elements to skip at the front of the array.
children: Child vectors as a list() coerced by as_narrow_array_data()
dictionary: Dictionary array for dictionary types.
x: An object to convert to an narrow_array
...: Passed to S3 Methods

Value

An object of class "narrow_array_data"
