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 RecordBatch
as_record_batch(x, ..., schema = NULL)
# S3 method for Table
as_record_batch(x, ..., schema = NULL)
# S3 method for data.frame
as_record_batch(x, ..., schema = NULL)
An object to convert to an Arrow RecordBatch
Passed to S3 methods
a Schema, or NULL
(the default) to infer the schema from
the data in ...
. When providing an Arrow IPC buffer, schema
is required.
# use as_record_batch() for a single object
as_record_batch(data.frame(col1 = 1, col2 = "two"))
#> RecordBatch
#> 1 rows x 2 columns
#> $col1 <double>
#> $col2 <string>
#>
#> See $metadata for additional Schema metadata
# use record_batch() to create from columns
record_batch(col1 = 1, col2 = "two")
#> RecordBatch
#> 1 rows x 2 columns
#> $col1 <double>
#> $col2 <string>
