<p>R 3.3.0, a major annual update to the <a target="_blank" href="https://mran.microsoft.com/documents/what-is-r/">R Language</a>, was released <a target="_blank" href="https://stat.ethz.ch/pipermail/r-announce/2016/000602.html">earlier this week</a> and is now available from your <a target="_blank" href="https://cran.r-project.org/mirrors.html">local CRAN mirror</a> for Windows, Mac (OSX 10.6 or later) and Linux systems. (Or as always, you can <a target="_blank" href="https://cran.r-project.org/doc/manuals/r-release/R-admin.html">build it yourself from sources</a>). This update — codenamed &quot;Supposedly Educational&quot; — makes a number of significant improvements to R, including:</p>
<ul>
<li>Support on all platforms for downloading data from secure HTTPS-enabled sites using <code>download.file</code> </li>
<li>A new function <code>sigma</code> to calculate residual standard deviation for a variety of statistical models</li>
<li><a target="_blank" href="http://revolution-computing.typepad.com/.a/6a010534b1db25970b01b7c852efbd970b-pi"><img title="Rlogo" alt="Rlogo" src="http://revolution-computing.typepad.com/.a/6a010534b1db25970b01b7c852efbd970b-120wi"></a>Speed improvements for a number of low-level R functions (which are in turn called my many higher-level functions, and likely your own R code). These include speedups for vector selection with boolean data, function argument matching, sorting vectors, and finding a single value in a vector with <code>match</code>  </li>
<li>R now includes a new, high-performance radix sort algorithm. This algorithm was contributed by Matt Dowle, who used it to make the data.table package fast, and now it's available to all R developers.</li>
<li>R's icons are now based on the new &quot;flat&quot; version of the R logo (thanks to an SVG version contributed by RStudio)</li>
<li>Packages built using C++11 code are now supported on Windows</li>
<li>Various bug fixes, including one that could sometimes cause R to crash when it runs out of resources.</li>
</ul>
<p>As this is a major release, you'll need to re-install any packages you were using (and perhaps wait a little while until package authors make any compatibility fixes needed for version 3.3.0). If you're on the Windows platform, <a target="_blank" href="http://www.r-statistics.com/2016/05/r-3-3-0-is-released/">Tal Galili's installR package</a> automates the process for you. If you are using the <a target="_blank" href="https://mran.microsoft.com/documents/rro/reproducibility/#timemachine">checkpoint package</a> (on any platform) you can simply increment the checkpoint date to anytime after May 2, 2016.</p>
<p>(For <a target="_blank" href="https://mran.microsoft.com/open/">Microsoft R Open</a> users, the next version to be released will be MRO 3.2.5, and MRO 3.3.0 will follow soon thereafter.)</p>
