# DataFrame.Slice

A set of a data frame’s rows you create by using a method from a data frame instance or another data frame slice.

## Declaration

```swift
@dynamicMemberLookup struct Slice
```

## Overview

Overview A slice is an arbitrary set of rows from a data frame. For example, a slice might contain rows 0–3, 5–9, and 101 from its underlying data frame.
