sdf_separate_column

Given a vector column in a Spark DataFrame, split that
into <code>n</code> separate columns, each column made up of
the different elements in the column <code>column</code>.

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.
