+<h2>Download and Install Apache Spark to a Local Directory</h2>
+
+<h3>Description</h3>
+
+<p><code>install.spark</code> downloads and installs Spark to a local directory if
+it is not found. If SPARK_HOME is set in the environment, and that directory is found, that is
+returned. The Spark version we use is the same as the SparkR version. Users can specify a desired
+Hadoop version, the remote mirror site, and the directory where the package is installed locally.
+</p>
+
+
+<h3>Usage</h3>
+
+<pre>
+install.spark(hadoopVersion = "2.7", mirrorUrl = NULL, localDir = NULL,
+  overwrite = FALSE)
+</pre>
+
+
+<h3>Arguments</h3>
+
+<table summary="R argblock">
+<tr valign="top"><td><code>hadoopVersion</code></td>
+<td>
+<p>Version of Hadoop to install. Default is <code>"2.7"</code>. It can take other
+version number in the format of &quot;x.y&quot; where x and y are integer.
+If <code>hadoopVersion = "without"</code>, &quot;Hadoop free&quot; build is installed.
+See
+<a href="http://spark.apache.org/docs/latest/hadoop-provided.html">
+&quot;Hadoop Free&quot; Build</a> for more information.
+Other patched version names can also be used, e.g. <code>"cdh4"</code></p>
+</td></tr>
+<tr valign="top"><td><code>mirrorUrl</code></td>
+<td>
+<p>base URL of the repositories to use. The directory layout should follow
+<a href="http://www.apache.org/dyn/closer.lua/spark/">Apache mirrors</a>.</p>
+</td></tr>
+<tr valign="top"><td><code>localDir</code></td>
+<td>
+<p>a local directory where Spark is installed. The directory contains
+version-specific folders of Spark packages. Default is path to
+the cache directory:
+</p>
+
+<ul>
+<li><p> Mac OS X: &lsquo;<span class="file">~/Library/Caches/spark</span>&rsquo;
+</p>
+</li>
+<li><p> Unix: <span class="env">$XDG_CACHE_HOME</span> if defined, otherwise &lsquo;<span class="file">~/.cache/spark</span>&rsquo;
+</p>
+</li>
+<li><p> Windows: &lsquo;<span class="file">%LOCALAPPDATA%\Apache\Spark\Cache</span>&rsquo;.
+</p>
+</li></ul>
+</td></tr>
+<tr valign="top"><td><code>overwrite</code></td>
+<td>
+<p>If <code>TRUE</code>, download and overwrite the existing tar file in localDir
+and force re-install Spark (in case the local directory or file is corrupted)</p>
+</td></tr>
+</table>
+
+
+<h3>Details</h3>
+
+<p>The full url of remote file is inferred from <code>mirrorUrl</code> and <code>hadoopVersion</code>.
+<code>mirrorUrl</code> specifies the remote path to a Spark folder. It is followed by a subfolder
+named after the Spark version (that corresponds to SparkR), and then the tar filename.
+The filename is composed of four parts, i.e. [Spark version]-bin-[Hadoop version].tgz.
+For example, the full path for a Spark 2.0.0 package for Hadoop 2.7 from
+<code>http://apache.osuosl.org</code> has path:
+<code>http://apache.osuosl.org/spark/spark-2.0.0/spark-2.0.0-bin-hadoop2.7.tgz</code>.
+For <code>hadoopVersion = "without"</code>, [Hadoop version] in the filename is then
+<code>without-hadoop</code>.
+</p>
+
+
+<h3>Value</h3>
+
+<p>the (invisible) local directory where Spark is found or installed
+</p>
+
+
+<h3>Note</h3>
+
+<p>install.spark since 2.1.0
+</p>
+
+
+<h3>See Also</h3>
+
+<p>See available Hadoop versions:
+<a href="http://spark.apache.org/downloads.html">Apache Spark</a>
+</p>

+<h3>Examples</h3>

+##D install.spark()
+## End(Not run)
