R: Pivot a Spark DataFrame

sdf_pivot {sparklyr} | R Documentation

## Pivot a Spark DataFrame

### Description

Construct a pivot table over a Spark Dataframe, using a syntax similar to that from `reshape2::dcast`.

### Usage

    sdf_pivot(x, formula, fun.aggregate = "count")

### Arguments

`x` | A `spark_connection`, `ml_pipeline`, or a `tbl_spark`.
`formula` | A two-sided R formula of the form `x_1 + x_2 + ... ~ y_1`. The left-hand side of the formula indicates which variables are used for grouping, and the right-hand side indicates which variable is used for pivoting. Currently, only a single pivot column is supported.
`fun.aggregate` | How should the grouped dataset be aggregated? Can be a length-one character vector, giving the name of a Spark aggregation function to be called; a named R list mapping column names to an aggregation method, or an R function that is invoked on the grouped dataset.
