Writing data to RDA and RDS files
=================================

An example showing how to write dataframes to RDA and RDS files.

Let's import Pandas to create dataframe and rdata to write to file.

.. GENERATED FROM PYTHON SOURCE LINES 13-18

.. code-block:: Python


    import pandas as pd

Let's create a toy dataframe

.. GENERATED FROM PYTHON SOURCE LINES 20-27

.. code-block:: Python


    data = pd.DataFrame({
        "class": pd.Categorical(["a", "b", "b"]),
        "value": [1, 2, 3],
    })
    data

Let's write this dataframe to an RDS file.

.. GENERATED FROM PYTHON SOURCE LINES 29-32

.. code-block:: Python


    rdata.write_rds("data.rds", data)








.. GENERATED FROM PYTHON SOURCE LINES 33-35

By default, the file is written in a binary XDR format with gzip compression.
We can write the file in different formats and compressions too.

.. GENERATED FROM PYTHON SOURCE LINES 35-39

.. code-block:: Python


    rdata.write_rds("data_uncompressed.rds", data, compression=None)
    rdata.write_rds("data_ascii.rds", data, file_format="ascii", compression=None)








.. GENERATED FROM PYTHON SOURCE LINES 40-41

We can also write multiple variables with given names to an RDA file.

.. GENERATED FROM PYTHON SOURCE LINES 41-53

.. code-block:: Python


    df1 = pd.DataFrame({
        "class": pd.Categorical(["a", "b", "b"]),
        "value": [1, 2, 3],
    })
    df2 = pd.DataFrame({
        "color": ["red", "green", "blue"],
        "count": [12, 34, 56],
    })
    data = {"df1": df1, "df2": df2}

    rdata.write_rda("data.rda", data)
