+<h2>Random Forest Model for Regression and Classification</h2>
+
+<h3>Description</h3>
+
+<p><code>spark.randomForest</code> fits a Random Forest Regression model or Classification model on
+a SparkDataFrame. Users can call <code>summary</code> to get a summary of the fitted Random Forest
+model, <code>predict</code> to make predictions on new data, and <code>write.ml</code>/<code>read.ml</code> to
+save/load fitted models.
+For more details, see
+<a href="http://spark.apache.org/docs/latest/ml-classification-regression.html#random-forest-regression">

+
+<h3>Details</h3>
+
+<p>This is a low level function to access the JVM directly and should only be used
+for advanced use cases. The arguments and return values that are primitive R
+types (like integer, numeric, character, lists) are automatically translated to/from
+Java types (like Integer, Double, String, Array). A full list can be found in
+serialize.R and deserialize.R in the Apache Spark code base.
+</p>
+
+
+<h3>Value</h3>
+
+<p>the return value of the Java method. Either returned as a R object
+if it can be deserialized or returned as a "jobj". See details section for more.

+<h2>Call Static Java Methods</h2>
+
+<h3>Description</h3>
+
+<p>Call a static method in the JVM running the Spark driver. The return
+value is automatically converted to R objects for simple objects. Other
+values are returned as "jobj" which are references to objects on JVM.

+types (like integer, numeric, character, lists) are automatically translated to/from

+serialize.R and deserialize.R in the Apache Spark code base.
+</p>
+
+
+<h3>Value</h3>
+

+

+SparkSession or initializes a new SparkSession.
+Additional Spark properties can be set in <code>...</code>, and these named parameters take priority
+over values in <code>master</code>, <code>appName</code>, named lists of <code>sparkConfig</code>.
+</p>

+<h3>Usage</h3>
+
+<pre>
+sparkR.session(master = "", appName = "SparkR",
+ sparkHome = Sys.getenv("SPARK_HOME"), sparkConfig = list(),
+ sparkJars = "", sparkPackages = "", enableHiveSupport = TRUE, ...)

+<tr valign="top"><td><code>master</code></td>

+</td></tr>
+</table>
+
+
+<h3>Details</h3>
+
+<p>When called in an interactive session, this method checks for the Spark installation, and, if not
+found, it will be downloaded and cached automatically. Alternatively, <code>install.spark</code> can
+be called manually.
+</p>
+<p>A default warehouse is created automatically in the current directory when a managed table is
+created via <code>sql</code> statement <code>CREATE TABLE</code>, for example. To change the location of the
+warehouse, set the named parameter <code>spark.sql.warehouse.dir</code> to the SparkSession. Along with
+the warehouse, an accompanied metastore may also be automatically created in the current
+directory when a new SparkSession is initialized with <code>enableHiveSupport</code> set to
+<code>TRUE</code>, which is the default. For more details, refer to Hive configuration at
+<a href="http://spark.apache.org/docs/latest/sql-programming-guide.html#hive-tables">http://spark.apache.org/docs/latest/sql-programming-guide.html#hive-tables</a>.
+</p>
+<p>For details on how to initialize and use SparkR, refer to SparkR programming guide at
