Generate random samples from the standard normal distribution

Description

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

Usage

  num_partitions = NULL,
  seed = NULL,
  output_col = "x"
)

Arguments

sc	A Spark connection.
n	Sample Size (default: 1000).
