在R脚本中将代码拆分为多行 [英] Split code over multiple lines in an R script

问题描述

我想将R脚本中的一行分割成多行(因为它太长了).我该怎么办?

I want to split a line in an R script over multiple lines (because it is too long). How do I do that?

具体来说，我有一行

setwd('~/a/very/long/path/here/that/goes/beyond/80/characters/and/then/some/more')

是否可以将长路径分成多行?我尝试过

Is it possible to split the long path over multiple lines? I tried

setwd('~/a/very/long/path/here/that/goes/beyond/80/characters/and/
then/some/more')

在第一行的末尾使用return键进行

；但这不起作用.

with return key at the end of the first line; but that does not work.

谢谢.

推荐答案

您不是在多行上破坏 code ，而是单个标识符.有区别.

You are not breaking code over multiple lines, but rather a single identifier. There is a difference.

对于您的问题，请尝试

R> setwd(paste("~/a/very/long/path/here",
               "/and/then/some/more",
               "/and/then/some/more",
               "/and/then/some/more", sep=""))

这也说明跨多行破坏代码是完全可以的.

which also illustrates that it is perfectly fine to break code across multiple lines.
