R: Slice a data frame into groups of rows

slice_rows {purrr} | R Documentation

## Slice a data frame into groups of rows

### Description

`slice_rows()` is equivalent to dplyr's `group_by()` command but it takes a vector of column names or positions instead of capturing column names with special evaluation. `unslice()` removes the slicing attributes.

### Usage

    slice_rows(.d, .cols = NULL)

    unslice(.d)

### Arguments

`.d` | A data frame to slice or unslice.
`.cols` | A character vector of column names or a numeric vector of column positions. If `NULL`, the slicing attributes are removed.

### Value

A sliced or unsliced data frame.
