[R] as.character(quote(x$y) ) = "$" "x" "y" not "x$y"?
Hello, All:
Is there a simple utility someplace to convert "quote(x$y)" to
"x$y"?
I ask, because as.character(quote(x$y)) is a character vector of
length 3 = "$" "x" "y". I want to convert this
to "x$y" for a
diagnostic message.
class(quote(x$y)) = "call", which suggests I could write
"as.character.call" to perform this function. However, before I do, I
felt a need to ask for other thoughts on this.
Thanks,
Spencer
