sdf_rpois

Generator method for creating a single-column Spark dataframes comprised of
i.i.d. samples from a Poisson distribution.

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.
