[R] name of object in quotes

[Bill.Venables at csiro.au]

This is a long-standing idiom:

> foo <- function(xvar) deparse(substitute(xvar))
> foo(x1)
[1] "x1"

Subject: [R] name of object in quotes

I am writing a function in which, at some point, I to recuperate the
name of a previous object in quotes. I am currently using the function
Cs() from the Hmisc library but the result is:

foo <- function(xvar) {
    variable <- Cs(xvar)
    return(variable)
}

foo(x1)
> "xvar"

when I would expected to obtain "x1".

Any suggestion?

Thanks
