R help - Sep 2008 - How to disable character escaping ?

Dear all,

	I have a string (a file path in windows system) contains several
"\"s.
When I copy and paste it into R for assignment to an variable, the
"\"s
are always interpreted as escaping characters. How can I keep it intact? 
Thanks.

Regards,
Leon

By reading from a file or connection, as in

foo <- scan("", "", n=1)
c:\tmp\foo

The parser always interprets \ in strings, so you must avoid the parser.
