Convert an object to an Arrow Table

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

Usage

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

# Default S3 method
as_arrow_table(x, ...)

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

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

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

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

# S3 method for class 'Dataset'
as_arrow_table(x, ...)

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

# S3 method for class 'Schema'
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>
