In sparklyr: R Interface to Apache Spark

Generate random samples from the uniform distribution U(0, 1).

Description

Generator method for creating a single-column Spark dataframes comprised of i.i.d. samples from the uniform distribution U(0, 1).

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

Arguments

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