R equivalent for .NET's Environment.NewLine

问题

Is there an R equivalent for Environment.NewLine in .NET?

I'm looking for a character object that would represent a new line based on the environment, e.g. CR LF ("\r\n") on Windows and LF ("\n") on Unix. I couldn't find any such thing in the R documentation, or the default R options.

回答1:

There’s no equivalent, but most of the time you won’t need it: as long as you’re writing to a text connection, the operating system will do the correct thing and treat '\n' according to the platform’s specification; for example, the documentation of writeLines says:

Normally writeLines is used with a text-mode connection, and the default separator is converted to the normal separator for that platform (LF on Unix/Linux, CRLF on Windows).

回答2:

The \n should still work:

> s = "line 1\nline 2"
> cat(s)
line 1
line 2

Here's a separate question which explains that print(s) doesn't quite work when trying to output strings with escape characters, and we should use cat or writeLine instead: Printing newlines with print() in R
