R自带数据集介绍
|
在用R语言做数据分析的时候，我们经常需要一些数据做实验，尤其当学会一个新的方法或者算法的时候，就想赶快编程实现一下。那么，问题来了，用什么数据好呢，什么样的数据适合做这种实验呢？ 好在R语言提供了很多的基本数据集，这些基本数据集是可以直接加载、可以完成几乎所有的数据分析任务模拟数据的。这都是些哪些种类的数据呢？ 之前我们安装了 ggplot2 会使用其默认数据集，其实R语言自带也是有数据集的。 data(package = 'ggplot2')
R自带基本数据集都在R包datasets里面，可以执行命令： data(package = 'datasets')
就会datasets包带的出现所有基本基本数据集：
