tidyverse introduction

The tidyverse is an opinionated collection of R packagesdesigned for data science. All packages share an underlying philosophy and common APIs.

大部分数据分析任务，通常有一些固定的操作，操作对应的命令和library也是相对固定的：

首先，导入数据→整理数据，然后进入：转换数据→数据图像化→建立模型这三者的循环中，同时需要一些操作让我们的代码更简洁。在这个过程中，我们经常会用到相应的很多library，悲剧的是我们经常会因为忘记载入相应的包而出现一系列的报错。是时候拿出大杀器tidyverse了。

tidyverse包一言以蔽之就是：Tidyverse是一个集成的系统包，里面包含了众多用作数据处理分析的library，并且持续更新中。载入这个包，你就可以高枕无忧了，以上所有命令随意用。哈哈哈哈
