In sparklyr: R Interface to Apache Spark

Generate random samples from a Poisson distribution

Description

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

Usage

sdf_rpois(sc, n, lambda, num_partitions = NULL, seed = NULL, output_col = "x")

n	Sample Size (default: 1000).

num_partitions	Number of partitions in the resulting Spark dataframe (default: default parallelism of the Spark cluster).
seed	Random seed (default: a random long integer).
output_col	Name of the output column containing sample values (default: "x").
