Convert an object to an Arrow RecordBatch — as_record_batch • Arrow R Package

Whereas record_batch() constructs a RecordBatch from one or more columns, as_record_batch() converts a single object to an Arrow RecordBatch.

Usage

as_record_batch(x, ..., schema = NULL)

# S3 method for RecordBatch
as_record_batch(x, ..., schema = NULL)

# S3 method for Table
as_record_batch(x, ..., schema = NULL)

# S3 method for arrow_dplyr_query
as_record_batch(x, ...)

# S3 method for data.frame
as_record_batch(x, ..., schema = NULL)

Arguments

x: An object to convert to an Arrow RecordBatch
...: Passed to S3 methods
schema: a Schema, or NULL (the default) to infer the schema from the data in .... When providing an Arrow IPC buffer, schema is required.
