Convert an object to an Arrow Table — as_arrow

Whereas arrow_table() constructs a table from one or more columns, as_arrow_table() converts a single object to an Arrow Table.

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

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

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

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

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

# S3 method for RecordBatchReader
as_arrow_table(x, ...)

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

Arguments

x: An object to convert to an Arrow Table
...: 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 Table

Examples

# use as_arrow_table() for a single object
as_arrow_table(data.frame(col1 = 1, col2 = "two"))
#> Table
#> 1 rows x 2 columns
#> $col1 <double>
#> $col2 <string>
#> 
#> See $metadata for additional Schema metadata

# use arrow_table() to create from columns
arrow_table(col1 = 1, col2 = "two")
#> Table
#> 1 rows x 2 columns
#> $col1 <double>
#> $col2 <string>
