<p>The goal of this project is to bring the blazingly fast <a href="https://www.pola.rs/" class="external-link">Polars</a> data manipulation library to R. The underlying computation engine is written in Rust and this R implementation has no other dependencies than R itself (≥ 4.1.0).</p>
<p>Documentation can be found on the <strong>r-polars</strong> <a href="https://rpolars.github.io/reference/index.html">homepage</a>.</p>
<p>The primary developer of the upstream Polars project is Ritchie Vink (<a href="https://github.com/ritchie46" class="external-link">@ritchie46</a>). This R port is maintained by Søren Welling (<a href="https://github.com/sorhawell" class="external-link">@sorhawell</a>), together with other <a href="https://github.com/pola-rs/r-polars/graphs/contributors" class="external-link">contributors</a>. Consider joining our <a href="https://discord.gg/4UfP5cfBE7" class="external-link">Discord</a> (subchannel) for additional help and discussion.</p>
<p><strong>Update:</strong> As of March 2023, <strong>polars</strong> has now reached nearly 100% coverage of the underlying “lazy” Expr syntax. While translation of the “eager” syntax is still a little further behind, you should be able to do just about everything using <code>$select()</code> + <code>$with_columns()</code>.</p>

<p>We also provide pre-compiled binaries for various operating systems, as well as source installs, on our <a href="https://github.com/pola-rs/r-polars/releases" class="external-link">GitHub releases</a> page. You can download and install these files manually, or install directly from R. Simply match the URL for your operating system and the desired release. For example, to install the latest release of <strong>polars</strong> on Linux (x86_64) one would use:</p>
<div class="sourceCode hasCopyButton" id="cb2"><button type="button" class="btn btn-primary btn-copy-ex" aria-label="Copy to clipboard" data-toggle="tooltip" data-placement="left" data-trigger="hover" data-clipboard-copy="" data-bs-original-title="Copy to clipboard"><i class="fa fa-copy"></i></button><pre class="downlit sourceCode r"><code class="sourceCode R"><span><span class="fu"><a href="https://rdrr.io/r/utils/install.packages.html" class="external-link">install.packages</a></span><span class="op">(</span></span>
<span>  <span class="st">"https://github.com/pola-rs/r-polars/releases/latest/download/polars__x86_64-pc-linux-gnu.gz"</span>,</span>
<span>  repos <span class="op">=</span> <span class="cn">NULL</span> </span>
<span><span class="op">)</span></span></code></pre></div>
<p>Similarly for Windows (<a href="https://github.com/pola-rs/r-polars/releases/latest/download/polars.zip" class="external-link">URL</a> and MacOS (x86_64, <a href="https://github.com/pola-rs/r-polars/releases/latest/download/polars__x86_64-apple-darwin17.0.tgz" class="external-link">URL</a>). Just remember to invoke the <code>repos = NULL</code> argument if you are installing these binary builds directly from within R.</p>
<p>One exception worth noting is MacOS (arm64), i.e.&nbsp;systems based on the new M1/M2 “Silicon” chips. To install <strong>polars</strong> on one of these machines, we need to build the package from source and this requires <a href="https://developer.apple.com/xcode/" class="external-link">Xcode</a> (<code>xcode-select --install</code>). Once Xcode is installed, you can run the below code chunk to build <strong>polars</strong>. The corresponding <code>Makevars</code> script will download a ~200MB cross-compiled object file, while your machine links and builds the final R package.</p>
<div class="sourceCode hasCopyButton" id="cb3"><button type="button" class="btn btn-primary btn-copy-ex" aria-label="Copy to clipboard" data-toggle="tooltip" data-placement="left" data-trigger="hover" data-clipboard-copy="" data-bs-original-title="Copy to clipboard"><i class="fa fa-copy"></i></button><pre class="downlit sourceCode r"><code class="sourceCode R"><span><span class="co"># install.packages("remotes")</span></span>

<div class="sourceCode hasCopyButton" id="cb8"><button type="button" class="btn btn-primary btn-copy-ex" aria-label="Copy to clipboard" data-toggle="tooltip" data-placement="left" data-trigger="hover" data-clipboard-copy="" data-bs-original-title="Copy to clipboard"><i class="fa fa-copy"></i></button><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb8-1"><a href="#cb8-1" aria-hidden="true" tabindex="-1"></a><span class="fu">git</span> clone git@github.com:<span class="op">&lt;</span>YOUR-GITHUB-ACCOUNT<span class="op">&gt;</span>/r-polars.git</span>
<span id="cb8-2"><a href="#cb8-2" aria-hidden="true" tabindex="-1"></a><span class="bu">cd</span> r-polars</span></code></pre></div>
<p><strong>Step 2:</strong> Build the package and install the suggested package dependencies.</p>
<ul>
<li>
<p>Option A: Using <strong>devtools</strong>.</p>
<div class="sourceCode hasCopyButton" id="cb9"><button type="button" class="btn btn-primary btn-copy-ex" aria-label="Copy to clipboard" data-toggle="tooltip" data-placement="left" data-trigger="hover" data-clipboard-copy="" data-bs-original-title="Copy to clipboard"><i class="fa fa-copy"></i></button><pre class="sourceCode r"><code class="sourceCode r"><span id="cb9-1"><a href="#cb9-1" aria-hidden="true" tabindex="-1"></a>Rscript <span class="sc">-</span>e <span class="st">'devtools::install(pkg = ".", dependencies = TRUE)'</span> </span></code></pre></div>
</li>
<li>
<p>Option B: Using <strong>renv</strong>.</p>
<div class="sourceCode hasCopyButton" id="cb10"><button type="button" class="btn btn-primary btn-copy-ex" aria-label="Copy to clipboard" data-toggle="tooltip" data-placement="left" data-trigger="hover" data-clipboard-copy="" data-bs-original-title="Copy to clipboard"><i class="fa fa-copy"></i></button><pre class="sourceCode r"><code class="sourceCode r"><span id="cb10-1"><a href="#cb10-1" aria-hidden="true" tabindex="-1"></a><span class="co"># Rscript -e 'install.packages("renv")'</span></span>
<span id="cb10-2"><a href="#cb10-2" aria-hidden="true" tabindex="-1"></a>Rscript <span class="sc">-</span>e <span class="st">'renv::activate(); renv::restore()'</span></span></code></pre></div>
</li>
</ul>
<p><strong>Step 3:</strong> Make your proposed changes to the R and/or Rust code. Don’t forget to run:</p>
<div class="sourceCode hasCopyButton" id="cb11"><button type="button" class="btn btn-primary btn-copy-ex" aria-label="Copy to clipboard" data-toggle="tooltip" data-placement="left" data-trigger="hover" data-clipboard-copy="" data-bs-original-title="Copy to clipboard"><i class="fa fa-copy"></i></button><pre class="downlit sourceCode r"><code class="sourceCode R"><span><span class="fu">rextendr</span><span class="fu">::</span><span class="fu"><a href="https://extendr.github.io/rextendr/reference/document.html" class="external-link">document</a></span><span class="op">(</span><span class="op">)</span> <span class="co"># compile Rust code + update wrappers &amp; docs</span></span>
<span><span class="fu">devtools</span><span class="fu">::</span><span class="fu"><a href="https://devtools.r-lib.org/reference/test.html" class="external-link">test</a></span><span class="op">(</span><span class="op">)</span>     <span class="co"># run all unit tests</span></span></code></pre></div>
<p><strong>Step 4 (optional):</strong> Build the package locally.</p>
<div class="sourceCode hasCopyButton" id="cb12"><button type="button" class="btn btn-primary btn-copy-ex" aria-label="Copy to clipboard" data-toggle="tooltip" data-placement="left" data-trigger="hover" data-clipboard-copy="" data-bs-original-title="Copy to clipboard"><i class="fa fa-copy"></i></button><pre class="sourceCode r"><code class="sourceCode r"><span id="cb12-1"><a href="#cb12-1" aria-hidden="true" tabindex="-1"></a>R CMD INSTALL <span class="sc">--</span>no<span class="sc">-</span>multiarch <span class="sc">--</span>with<span class="sc">-</span>keep.source polars</span></code></pre></div>
<p><strong>Step 5:</strong> Commit your changes and submit a PR to the main <strong>polars</strong> repo.</p>
<ul>
<li>As aside, notice that <code>./renv.lock</code> sets all R packages during the server build.</li>
</ul>
<p><em>Tip:</em> To speed up the local R CMD check, run the following:</p>
<div class="sourceCode hasCopyButton" id="cb13"><button type="button" class="btn btn-primary btn-copy-ex" aria-label="Copy to clipboard" data-toggle="tooltip" data-placement="left" data-trigger="hover" data-clipboard-copy="" data-bs-original-title="Copy to clipboard"><i class="fa fa-copy"></i></button><pre class="downlit sourceCode r"><code class="sourceCode R"><span><span class="fu">devtools</span><span class="fu">::</span><span class="fu"><a href="https://devtools.r-lib.org/reference/check.html" class="external-link">check</a></span><span class="op">(</span></span>
<span>  env_vars <span class="op">=</span> <span class="fu"><a href="reference/Expr_list.html">list</a></span><span class="op">(</span>RPOLARS_RUST_SOURCE<span class="op">=</span><span class="st">"/YOUR/OWN/ABSOLUTE/PATH/r-polars/src/rust"</span><span class="op">)</span>,</span>
<span>  check_dir <span class="op">=</span> <span class="st">"./check/"</span></span>
<span>  <span class="op">)</span></span>
<span><span class="kw"><a href="https://rdrr.io/r/base/source.html" class="external-link">source</a></span><span class="op">(</span><span class="st">"./inst/misc/filter_rcmdcheck.R"</span><span class="op">)</span></span>
<span><span class="fu"><a href="https://rdrr.io/r/base/Sys.sleep.html" class="external-link">Sys.sleep</a></span><span class="op">(</span><span class="fl">5</span><span class="op">)</span></span>
<span><span class="fu"><a href="https://rdrr.io/r/base/unlink.html" class="external-link">unlink</a></span><span class="op">(</span><span class="st">"check"</span>,recursive <span class="op">=</span> <span class="cn">TRUE</span>, force <span class="op">=</span><span class="cn">TRUE</span><span class="op">)</span></span></code></pre></div>
<ul>
<li>The <code>RPOLARS_RUST_SOURCE</code> environment variable allows <strong>polars</strong> to recover the Cargo cache even if source files have been moved. Replace with your own absolute path to your local clone!</li>
<li>
<code>filter_rcmdcheck.R</code> removes known warnings from final check report.</li>
<li>
<code>unlink("check")</code> cleans up.</li>
