To explain: the first sentence is used in summary tables on the API pages, so this is not what we want to show there.

Split each string (a la re.split) in array by given pattern, propagating NA

Can you add puntcuation? (so a . at the end of the line) -> when converted to html, the line breaks are not preserved as in raw text here.

Also, can you quote expand (like 'expand'), then it is clearer it is the value you give to the argument.

If series, index or same, returns the same type as the original object

I would only mention 'same' here (as you did for 'frame')

(elements are lists of strings).
