Whereas record_batch() constructs a RecordBatch from one or more columns, as_record_batch() converts a single object to an Arrow RecordBatch.
as_record_batch(x, ..., schema = NULL) # S3 method for class 'RecordBatch' as_record_batch(x, ..., schema = NULL) # S3 method for class 'Table' as_record_batch(x, ..., schema = NULL) # S3 method for class 'arrow_dplyr_query' as_record_batch(x, ...) # S3 method for class 'data.frame' as_record_batch(x, ..., schema = NULL)
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.
