Parsing code with newlines
?\r" is CR not LF. On systems that use CRLF as newline, the combination should be "\n" at the C (or R) level. However, I suppose there is no particular reason not to treat CR as whitespace, as does happen with FF and HT. -pd

It is reproducible from R console as well. ,----[ R console session ] | > parse(text="\r\n ls()") | Error in parse(text = "\r\n ls()") : <text>:1:1: unexpected input | 1: | ^ | > `----
