Use substitute(argumentName) to get the literal argument, as a language object,
and deparse() to convert that into a character vector. That vector could be
quite
long (especially what your function is called via do.call) so you may want to
truncate it.
> doit2 <- function (data)
{
dataName
doit <- function(data) {
cat("This function is using values from the data frame",
deparse(substitute(data)), "\n")
}
