Description

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

Usage

  sc, 
  n, 
  mean = 0, 
  sd = 1, 
  num_partitions = NULL, 
  seed = NULL, 
  output_col = "x" 
) 

Arguments

Arguments	Description
sc	A Spark connection.
