Hi,
Suppose I have
x = parse(text = "
{y=50+50+50#'asfasf'
}
")
now x is an expression with some src attributes.
x
expression({y=50+50+50#'asfasf'
})
attr(,"srcfile")
<text>
attr(,"wholeSrcref")
{y=50+50+50#'asfasf'
}
My question is, how can I get my string back (the string passed to
parse() as the text argument)?
> attr(x, "wholeSrcref")
{y=50+50+50#'asfasf'
}

David.
as.character(x)
[1] "{"
as.character() only returns "{".
as.character(expression({1}))
[1] "{"
as.character(expression("1","2+3"))
[1] "1" "2+3"
Thanks a lot!
Regards,
Yihui
