DataFrame-js 为 javascript 和数据科学提供了一个不可变的数据结构，DataFrame，它允许使用 sql 和函数式编程启发的 api 处理行和列。

使用 DataFrame，你可以轻松地做大量复杂的事情，例如连接、分组、探索任务、机器学习……

它主要设计用于服务器端（使用节点），但它也可以用于浏览器（与文件系统无关）特征）。

示例：

import DataFrame from "dataframe-js";
import { data, columns } from "./titanic_data.js";
const df = new DataFrame(data, columns);
const filteredDf = df
    .filter(row => row.get("survived") === "yes")
    .select("class", "age", "sex");
filteredDf.show(3);

| class       | age        | sex        |
----------------------------------------
| 1st class   | adults     | man        |
| 1st class   | adults     | man        |
| 1st class   | adults     | woman      |

Installation

通过 git：npm install git+https://github.com/Gmousse/dataframe-js.git

通过 npm：npm install dataframe-js

通过 yarn：< code>yarn add dataframe-js

对于浏览器，我们更改了脚本提供程序 (rawgit)，因为它将关闭很快，考虑更新 url!!!

在浏览器 (1.4.0) 中：

for production <script src="https://gmousse.github.io/dataframe-js/dist/dataframe.min.js"></script> (~ 80ko)
for development <script src="https://gmousse.github.io/dataframe-js/dist/dataframe.js"></script> (~ 300ko)

DataFrame-js provides an immutable data structure for javascript and datascience, the DataFrame, which allows to work on rows and columns with a sql and functional programming inspired api.

With the DataFrame, you can easily do a ton of complex stuff such as join, groupby, exploration tasks, machine learning…

It's mainly designed to work on server-side (with node) but it also works in the browser (without file system related features).

Example:

import DataFrame from "dataframe-js";
import { data, columns } from "./titanic_data.js";
const df = new DataFrame(data, columns);
const filteredDf = df
    .filter(row => row.get("survived") === "yes")
    .select("class", "age", "sex");
filteredDf.show(3);

| class       | age        | sex        |
----------------------------------------
| 1st class   | adults     | man        |
| 1st class   | adults     | man        |
| 1st class   | adults     | woman      |

Installation

via git: npm install git+https://github.com/Gmousse/dataframe-js.git

via npm: npm install dataframe-js

via yarn: yarn add dataframe-js

For the browser, we have change the script provider (rawgit) because it will close soon, consider to update the url!!!

in the browser (1.4.0):

for production <script src="https://gmousse.github.io/dataframe-js/dist/dataframe.min.js"></script> (~ 80ko)
for development <script src="https://gmousse.github.io/dataframe-js/dist/dataframe.js"></script> (~ 300ko)
