About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Datasets

Datasets.

Installation

npm install @stdlib/datasets

Usage

var datasets = require( '@stdlib/datasets' );

datasets( name[, options] )

Returns standard library datasets.

var data = datasets( 'MONTH_NAMES_EN' );
/* returns
    [
        'January',
        'February',
        'March',
        'April',
        'May',
        'June',
        'July',
        'August',
        'September',
        'October',
        'November',
        'December'
    ]
*/

The function forwards provided options to the dataset interface specified by name.

var opts = {
    'data': 'cities'
};

var data = datasets( 'MINARD_NAPOLEONS_MARCH', opts );
/* returns
    [
        {'lon': 24,'lat': 55,'city': 'Kowno',
        {'lon': 25.3,'lat': 54.7,'city': 'Wilna',
        {'lon': 26.4,'lat': 54.4,'city': 'Smorgoni',
        {'lon': 26.8,'lat': 54.3,'city': 'Molodexno',

        {'lon': 30.4,'lat': 53.9,'city': 'Mohilow',
        {'lon': 32,'lat': 54.8,'city': 'Smolensk',
        {'lon': 33.2,'lat': 54.9,'city': 'Dorogobouge',

        {'lon': 36,'lat': 55.5,'city': 'Mojaisk',
        {'lon': 37.6,'lat': 55.8,'city': 'Moscou',
        {'lon': 36.6,'lat': 55.3,'city': 'Tarantino',
        {'lon': 36.5,'lat': 55,'city': 'Malo-Jarosewli'
    ]

Examples

var datasets = require( '@stdlib/datasets' );

var data = datasets( 'MONTH_NAMES_EN' );
console.log( data );

CLI

Installation

To use as a general utility, install the CLI package globally

npm install -g @stdlib/datasets-cli

Usage

Usage: datasets [options] [--name=<name>]

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.
         --name name           Dataset name.
         --ls                  List datasets.

Notes

• Dataset specific options should follow two hyphen characters -- in order to indicate that those options should not be parsed as normal command-line options.

Examples

$ datasets --name MONTH_NAMES_EN
January
February
March
...

Use two hyphen characters -- to delineate dataset specific options.

$ datasets --name MINARD_NAPOLEONS_MARCH -- --data army
lon,lat,size,direction,division
24.0,54.9,340000,A,1
24.5,55.0,340000,A,1
25.5,54.5,340000,A,1
...
