How can I check documentation for R code from a Linux command shell such as bash? I DO NOT mean an interactive session.
如何检查来自Linux命令shell(如bash)的R代码文档?我指的不是交互式会话。
With Perl, I can use perldoc to print out documentation at the command line:
使用Perl，我可以使用perldoc在命令行打印文档:
perldoc libI was hoping for something simple like that for R. I don't always want to pull up a full interactive R session just to look up some documentation.
我希望在R中使用这样简单的东西，我并不总是想要打开一个完整的交互式R会话来查找一些文档。

There might be other ways, but one that works for me is using the -e flag to execute code on the command line. I also use the --slave flag, which prevents anything from being printed to standard output (e.g. no R startup messages, etc.):
可能还有其他的方法，但是对我来说最有效的方法是使用-e标志在命令行上执行代码。我还使用-slave标志，它阻止任何东西被打印到标准输出(例如没有R启动消息等):
R --slave -e '?function'I actually created a super small script I call rdoc to act like a simple R version of perldoc:
实际上我创建了一个超级小的脚本，我把它叫做rdoc，就像一个简单的R版本的perldoc:
#!/bin/bashR --slave -e "?$1"After installing that in my ~/bin directory (or however you install it in your PATH), it's easy:
在我的~/bin目录中安装之后(或者在您的路径中安装它)，很容易:
rdoc functionIf you want to look at documentation of a function from a particular package, prepend the library name followed by two colons. For example, to pull up documentation of the dmrFinder function from the charm package:
如果您想从一个特定的包中查看函数的文档，请先在库名称后面加上两个冒号。例如，从魅力包中提取dmrFinder函数的文档:
rdoc charm::dmrFinder#1
