R: Spark ML - Principal Components Analysis

ml_pca {sparklyr} | R Documentation

## Spark ML – Principal Components Analysis

### Description

Perform principal components analysis on a Spark DataFrame.

### Usage

    ml_pca(x, features = dplyr::tbl_vars(x), ml.options = ml_options(), ...)

### Arguments

`x` | An object coercable to a Spark DataFrame (typically, a `tbl_spark`).
`features` | The columns to use in the principal components analysis. Defaults to all columns in `x`.
`ml.options` | Optional arguments, used to affect the model generated. See `ml_options` for more details.
`...` | Optional arguments. The `data` argument can be used to specify the data to be used when `x` is a formula; this allows calls of the form `ml_linear_regression(y ~ x, data = tbl)`, and is especially useful in conjunction with `do`.
