Sample — sample • SparkR

Return a sampled subset of this SparkDataFrame using a random seed. Note: this is not guaranteed to provide exactly the fraction specified of the total count of of the given SparkDataFrame.

sample(x, withReplacement = FALSE, fraction, seed)

sample_frac(x, withReplacement = FALSE, fraction, seed)

# S4 method for class 'SparkDataFrame'
sample(x, withReplacement = FALSE, fraction, seed)

# S4 method for class 'SparkDataFrame'
sample_frac(x, withReplacement = FALSE, fraction, seed)

x

A SparkDataFrame

withReplacement

Sampling with replacement or not

fraction

The (rough) sample target fraction

seed

Randomness seed value. Default is a random seed.

sample since 1.4.0
