Parameters | Type | Description | Default |
|---|---|---|---|
rows | Array or String slice | Array, string slice, index of row positions boolean mask to filter by. | |
.iloc() is primarily integer position based (from 0 to length-1 of the axis).Allowed inputs are:
- An integer, e.g.
5. - A list or array of integers, e.g.
[4, 3, 0]. - A boolean mask. E.g [ true, false, false ]
- A string slice object with ints, e.g.
"1:7"
Note: only **** the start label is included, and the end label is ignored.
.iloc will raiseIndexError if a requested indexer is out-of-bounds.Node

const dfd = require("danfojs-node")
let s = new dfd.Series([12, 34, 2.2, 2, 30, 30, 2.1, 7])
s.iloc([0,5]).print()
Output

The iloc function also accepts string slices of the form [start: end], e.g "[0: 5]". This will return all values from index positions 0 to 4.
