Convert an object to an Arrow RecordBatch — as_record

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)

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.

Value

A RecordBatch

Examples

# 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>
