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.
Why manually edit? You can do this many ways, including with R (reading
from a file or from a separate line). E.g.
setwd(readline(new dir: ))
new dir: c:\TEMP
getwd()
[1] c:/TEMP
I did find a workable solution to this particular problem:
setwd(choose.dir())EnterPasteEnter
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?
No.

Re: [R] Non-interpreted strings
Enter this at the console
x - scan(what = )
and after pressing the enter after the right paren,
do a paste and then press enter twice.

Re: [R] Non-interpreted strings
Or even easier,
x - scan(clipboard, what = )
at least on Windows.
