Suppose I am writing a text file using the following code.
df <- iris
write.table(df, "data/iris.txt")
When I open the file in Notepad ++ , it displays CRLF.

If I replace \n with \r, it displays CR. If I do the opposite, it becomes LF. So my question is: How can I achieve CR or LF or CRLF directly from the write.table() ( or any other function)?
See https://npp-user-manual.org/docs/searching/#extended-search-mode to know about \n and \r.
