Series.iloc
danfo.Series.iloc()
Parameters
Type
Description
Default
rows
Array or String slice
Array, string slice, index of row positions boolean mask to filter by.

Examples

.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.

Indexing specific rows by index

Node
Browser
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
╔═══╤════╗
║ 0 │ 12 ║
╟───┼────╢
║ 5 │ 30 ║
╚═══╧════╝

Index by a slice of row

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.

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
╔═══╤═════╗
║ 0 │ 12 ║
╟───┼─────╢
║ 1 │ 34 ║
╟───┼─────╢
║ 2 │ 2.2 ║
╟───┼─────╢
║ 3 │ 2 ║
╟───┼─────╢
║ 4 │ 30 ║
╚═══╧═════╝
By specifying a start index in a slice, all values after that index are returned.

const dfd = require("danfojs-node")

Output
╔═══╤═════╗
║ 5 │ 30 ║

║ 6 │ 2.1 ║
╟───┼─────╢
║ 7 │ 7 ║

Slice Series by boolean condition

let s = new dfd.Series([12, 34, 2.2, 2, 30, 30, 2.1, 7])
s.iloc(s.gt(20)).print()
╔═══╤════╗
║ 1 │ 34 ║
