Is there an alternative to \n to split text onto a new line? \n creates a new paragraph, which can inherit extra spacing. A line break method would ensure next line was same paragraph - equivalent to Shift + Enter in Word. Does it exist as a programmatic character?
I've tagged R below, but the question seems equally valid for Python etc.
Considering the general case of flow documents, in theory line breaking is very complicated with different characters. In practice, applications or operating systems usually represent a newline with one or two control characters. For example Excel uses Left Feed or (as long as I know) word uses Vertical Tab to break. Therefore, there is no general rule in your case and it is completely application specific. In other words, you should not expect to generate a string, feed it to different environments and expect them to behave similarly.
