Generate random samples from a Poisson distribution




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


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


Arguments Description
sc A Spark connection.
n Sample Size (default: 1000).
lambda Mean, or lambda, of the Poisson distribution.
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”).
