3.
如果遇到困难，寻求帮助！将清晰的问题发布在合适地方，使用可重复的
代码，应该很快得到一个启发性的回答。
4.
对于深入学习，没有比实战演示的
R
书籍和教程更有效的了。做一些调查
并确定你该用的资源。
5.
巩固学习的最好的一个办法是写出来并传授，告诉你学到的知识同时也帮
助了他人。
使用
R
的内部帮助
有时寻求帮助最好的地方在
R
语言内，从效率角度来看使用
R
的帮助有三个
主要优势
：
•
在你的
IDE
内查询
R
比切换环境并在不同平台下（例如以太网，有大量
干扰信息）搜索帮助要快。
•
离线工作。
•
学会阅读
R
文档（以及源代码）是一个提高你编程水平的强大技能。
R
的内部帮助主要缺点是它简短并且有时稀少。不要希望总能在
R
中找到答案，
而应随时准备从他处寻求详细的帮助以及解释。从学习的角度，熟悉
R
的文
档通常好于从其他资源中寻求答案，因为
R
文档由代码作者编写，主要为开
发者所写。因此，使用
R
文档你相当于从作者本人那学习函数。
R
帮助有时
通过引用学术文献对函数的历史做了进一步说明。
当你想学习一个
R
的话题或函数，你可能有你自己的搜索办法，范围从宽到窄：
1.
搜索
R
以及安装包查找特定主题的帮助。
2.
阅读包的简介。
3.
查找特定函数的帮助。
4.
阅读源代码。
多数情况下，你可能已经经历了阶段

和阶段

。你常在阶段

停下来，简单
