Is there a way to make R strings verbatim (not escaped)?

Question

Typical example:

path <- "C:/test/path" # great
path <- "C:\\test\\path" # also great
path <- "C:\test\path"

Error: '\p' is an unrecognized escape in character string starting ""C:\test\p"

(of course - \t is actually an escape character.)

Is there any mark that can be used to treat the string as verbatim? Or can it be coded?

It would be really useful when copy/pasting path names in Windows...

R 4.0.0 introduces raw strings:

dir <- r"(c:\Program files\R)"
