| <h2>Invoking R functions from Python<a class="headerlink" href="#invoking-r-functions-from-python" title="Permalink to this heading">#</a></h2> |
| <p>Suppose we have a simple R function receiving an Arrow Array to |
| add <code class="docutils literal notranslate"><span class="pre">3</span></code> to all its elements:</p> |
| <div class="highlight-R notranslate"><div class="highlight"><pre><span></span><span class="nf">library</span><span class="p">(</span><span class="n">arrow</span><span class="p">)</span> |
| |
| <span class="n">addthree</span><span class="w"> </span><span class="o"><-</span><span class="w"> </span><span class="kr">function</span><span class="p">(</span><span class="n">arr</span><span class="p">)</span><span class="w"> </span><span class="p">{</span> |
| <span class="w"> </span><span class="kr">return</span><span class="p">(</span><span class="n">arr</span><span class="w"> </span><span class="o">+</span><span class="w"> </span><span class="m">3L</span><span class="p">)</span> |
| <span class="p">}</span> |
| </pre></div> |
| </div> |
| <p>We could save such a function in a <code class="docutils literal notranslate"><span class="pre">addthree.R</span></code> file so that we can |
| make it available for reuse.</p> |
| <p>Once the <code class="docutils literal notranslate"><span class="pre">addthree.R</span></code> file is created we can invoke any of its functions |
| from Python using the |
| <a class="reference external" href="https://rpy2.github.io/doc/latest/html/index.html">rpy2</a> library which |
| enables a R runtime within the Python interpreter.</p> |
| <p><code class="docutils literal notranslate"><span class="pre">rpy2</span></code> can be installed using <code class="docutils literal notranslate"><span class="pre">pip</span></code> like most Python libraries</p> |
| <div class="highlight-bash notranslate"><div class="highlight"><pre><span></span>$<span class="w"> </span>pip<span class="w"> </span>install<span class="w"> </span>rpy2 |
| </pre></div> |
| </div> |
| <p>The most basic thing we can do with our <code class="docutils literal notranslate"><span class="pre">addthree</span></code> function is to |
| invoke it from Python with a number and see how it will return the result.</p> |
| <p>To do so we can create an <code class="docutils literal notranslate"><span class="pre">addthree.py</span></code> file which uses <code class="docutils literal notranslate"><span class="pre">rpy2</span></code> to |
| import the <code class="docutils literal notranslate"><span class="pre">addthree</span></code> function from <code class="docutils literal notranslate"><span class="pre">addthree.R</span></code> file and invoke it:</p> |
| <div class="highlight-python notranslate"><div class="highlight"><pre><span></span><span class="kn">import</span><span class="w"> </span><span class="nn">rpy2.robjects</span><span class="w"> </span><span class="k">as</span><span class="w"> </span><span class="nn">robjects</span> |

| <span class="nb">print</span><span class="p">(</span><span class="n">value</span><span class="p">)</span> |
| </pre></div> |
| </div> |
| <p>Running the <code class="docutils literal notranslate"><span class="pre">addthree.py</span></code> file will show how our Python code is able |
| to access the <code class="docutils literal notranslate"><span class="pre">R</span></code> function and print the expected result:</p> |
| <div class="highlight-bash notranslate"><div class="highlight"><pre><span></span>$<span class="w"> </span>python<span class="w"> </span>addthree.py |
| <span class="m">6</span> |
| </pre></div> |
| </div> |
| <p>If instead of passing around basic data types we want to pass around |
| Arrow Arrays, we can do so relying on the |
| <a class="reference external" href="https://rpy2.github.io/rpy2-arrow/version/main/html/index.html">rpy2-arrow</a> |
| module which implements <code class="docutils literal notranslate"><span class="pre">rpy2</span></code> support for Arrow types.</p> |
| <p><code class="docutils literal notranslate"><span class="pre">rpy2-arrow</span></code> can be installed through <code class="docutils literal notranslate"><span class="pre">pip</span></code>:</p> |

| </div> |
| <p><code class="docutils literal notranslate"><span class="pre">rpy2-arrow</span></code> implements converters from PyArrow objects to R Arrow objects, |
| this is done without incurring any data copy cost as it relies on the |

| <p>To pass to the <code class="docutils literal notranslate"><span class="pre">addthree</span></code> function a PyArrow array, our <code class="docutils literal notranslate"><span class="pre">addthree.py</span></code> file needs to be modified |

| <p>Exposing Python functions to R can be done through the <code class="docutils literal notranslate"><span class="pre">reticulate</span></code> |

| <h2>R to Python communication using the C Data Interface<a class="headerlink" href="#r-to-python-communication-using-the-c-data-interface" title="Permalink to this heading">#</a></h2> |
| <p>Both solutions described above use the Arrow C Data |
| interface under the hood.</p> |
| <p>In case we want to extend the previous <code class="docutils literal notranslate"><span class="pre">addthree</span></code> example to switch |
| from using <code class="docutils literal notranslate"><span class="pre">rpy2-arrow</span></code> to using the plain C Data interface we can |
| do so by introducing some modifications to our codebase.</p> |
| <p>To enable importing the Arrow Array from the C Data interface we have to |
| wrap our <code class="docutils literal notranslate"><span class="pre">addthree</span></code> function in a function that does the extra work |
| necessary to import an Arrow Array in R from the C Data interface.</p> |
| <p>That work will be done by the <code class="docutils literal notranslate"><span class="pre">addthree_cdata</span></code> function which invokes the |
| <code class="docutils literal notranslate"><span class="pre">addthree</span></code> function once the Array is imported.</p> |
| <p>Our <code class="docutils literal notranslate"><span class="pre">addthree.R</span></code> will thus have both the <code class="docutils literal notranslate"><span class="pre">addthree_cdata</span></code> and the |
| <code class="docutils literal notranslate"><span class="pre">addthree</span></code> functions:</p> |
| <div class="highlight-R notranslate"><div class="highlight"><pre><span></span><span class="nf">library</span><span class="p">(</span><span class="n">arrow</span><span class="p">)</span> |

| <p>We can now provide to R the array and its schema from Python through the |
| <code class="docutils literal notranslate"><span class="pre">array_ptr_s</span></code> and <code class="docutils literal notranslate"><span class="pre">schema_ptr_s</span></code> arguments so that R can build back |
| an <code class="docutils literal notranslate"><span class="pre">Array</span></code> from them and then invoke <code class="docutils literal notranslate"><span class="pre">addthree</span></code> with the array.</p> |
| <p>Invoking <code class="docutils literal notranslate"><span class="pre">addthree_cdata</span></code> from Python involves building the Array we |
| want to pass to <code class="docutils literal notranslate"><span class="pre">R</span></code>, exporting it to the C Data interface and then |
| passing the exported references to the <code class="docutils literal notranslate"><span class="pre">R</span></code> function.</p> |
| <p>Our <code class="docutils literal notranslate"><span class="pre">addthree.py</span></code> will thus become:</p> |
