hof_exists

Determines whether an element satisfying the given predicate exists in each array from
an array column
(this is essentially a dplyr wrapper for the
<code>exists(array&lt;T&gt;, function&lt;T, Boolean&gt;): Boolean</code> built-in Spark SQL function)

R interface to Apache Spark, a fast and general
engine for big data processing, see <https://spark.apache.org/>. This
package supports connecting to local and remote Apache Spark clusters,
provides a 'dplyr' compatible back-end, and provides an interface to
Spark's built-in machine learning algorithms.
