推荐答案

R 的本质意味着当你简单地打印出来时，你永远不会在字符向量中出现换行符.

The nature of R means that you're never going to have a newline in a character vector when you simply print it out.

> print("hello
world
")
[1] "hello
world
"

也就是说，换行符是在字符串中，它们只是不会被打印为新行.但是，如果要打印它们，可以使用其他函数，例如 猫:

That is, the newlines are in the string, they just don't get printed as new lines. However, you can use other functions if you want to print them, such as cat:

> cat("hello
world
")
hello
world
