R - do I need to add explicit new line character with print()?

How do I use the new line character in R? 

myStringVariable <- "Very Nice ! I like";

myStringVariabel <- paste(myStringVariable, "\n", sep="");

The above code DOESN'T work

P.S There's significant challenges when googling this kind of stuff since the query "R new line character" does seem to confuse google. I really wish R had a different name.

You can also use writeLines.

> writeLines("hello\nworld")
hello
world

And also:

> writeLines(c("hello","world"))
hello
world

Example on NewLine Char:

for (i in 1:5)
  {
   for (j in 1:i)
    {
     cat(j)
    }
    cat("\n")
  }

Result:

    1
    12
    123
    1234
    12345

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\nworld\n")
[1] "hello\nworld\n"

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\nworld\n")
hello
world
