I am new to R, so please forgive me if there is an obvious answer to
this question.  I have done fairly extensive searching through R docs,
google and a few R users and have not found an answer to my question.

Is there a way to create a non-interpreted string object in R?

For example, I am using R in a MS Windows environment and I would like
to paste DOS paths into some R command:
	setwd("c:\some\directory")

Obviously this does not work because of the escaping mechanism.  And I
know the obvious answer, use "\\".  But if you do a lot of pasting into
R it could get tedious manually editing escape sequences.

I did find a workable solution to this particular problem:
	setwd(choose.dir())<Enter><Paste><Enter>
This saves me from having to do the editing myself.  I can conceive of
other examples of wanting to paste other more abstract stings into R
that may happen to have a \ in it.  And now, thanks to choose.dir(), I
have a way to do the translation automagically but...

My question is, is there any way in R to not interpret the string and
store the string as is?  For instance, Perl allows you to do interpreted
(" ") and non-interpreted strings (' ').  This does not work in R; ' '
acts just like " " and my testing indicates that the interpretation is
done at parse time.  Is there any language level construct for creating
a non-interpreted string in R?
