Intro to Dataset

Dataset allows you to load delimited files and parse them to convert them into Array of NArrays.

Usage

import toynn from 'toynn';

const myDataset = await toynn.Dataset.from('./iris.csv');

You can pass a path or a URL or an Array of NArray to the from function.

Static Functions

from

Signature: async from(loc: string | Array, options: DatasetOptions)

You can use this static function to create Dataset from, a path, an URL or Array of NArrays.

A file loaded from a URL is cached for 1 day.

Creating Dataset Object

You can directly use new Dataset(obj) to create a Dataset. You can only pass Array of NArray as the object inside Dataset constructor. If in case you want to load data from some file or URL you can use from('path') to load the data.

import toynn from 'toynn';

const obj = [new toynn.NArray([1, 2, 3, 4])];

const myDataset = new toynn.Dataset(obj);
// or
const myOtherDataset = await toynn.Dataset.from('someURLOrPath');

Dataset Options

These are the options that you can pass to from method.

delimiter?: string

While parsing this will be used to split a single line. Defaults to ’,‘

headerCol?: number

These many lines will be skipped when reading the data. Defaults to 1
