## 如何学习接下来的内容？
|
|
|
|
|
|
|
|
|
|
|
|
- 上课形式：
|
|
|
|
|
|
- **实践操作为主**，目的是让每一位同学都能独立开展基于R的数据分析
|
|
|
|
|
|
- **2-3人一组**，自由分组，相互帮助
|
|
|
|
|
|
- 准备工作：
|
|
|
|
|
|
- 个人笔记本电脑，Microsoft Windows、GNU/Linux、MacOS系统
|
|
|
|
|
|
- 安装好**Microsoft Excel**
|
|
|
|
|
|
- 能联网
|
|
|
|
|
|
- 如果电池不够用，建议带上插座
|
|
|
|
|
|
- 上课规则
|
|
|
|
|
|
- 可随时打断，**不懂就问**
|
|
|
|
|
|
- **无特殊情况不迟到**，否则操作过程容易跟不上

## Rstudio Server使用
|
|
|
|
|
|
|
|
|
|
|
|
- 服务网址：[https://drwater.rcees.ac.cn/rs1/](https://drwater.rcees.ac.cn/rs1/)
|
|
|
|
|
|
- 每位同学使用1个账号，随机生成
|
