sdf_quantile: Compute (Approximate) Quantiles with a Spark DataFrame
Description
Given a numeric column within a Spark DataFrame, compute
approximate quantiles (to some relative error).
Usage
sdf_quantile(x, column, probabilities = c(0, 0.25, 0.5, 0.75, 1), relative.error = 1e-05)
Arguments
x
An object coercable to a Spark DataFrame (typically, a
tbl_spark
).
column
The column for which quantiles should be computed.
probabilities
A numeric vector of probabilities, for
which quantiles should be computed.
relative.error
The relative error -- lower values imply more
precision in the computed quantiles.
