R help - Mar 2010 - colname of ... arguments

I have writtn a function where I pass a variable number of arguments.

I They are vectors and I can manipulate them, but I need to get hold of the
name for a legend.

niceplot<-function(...) {
   parms=list(...)

  for (x in parms) {
    DoSomethingWith(x)
  }

}

BUT how how can I get something like namestring(...) of nameofvector(x)?

I use the following syntax to get the name of a data object to use in a 
title, label or whatever.

xname <- paste(deparse(substitute(x), 500), collapse = "\n")

This is taken from hist.default so at least has some provenance as an 
appropriate method.

I think you need to provide a richer example:

niceplot<-function(...) {
   parms=list(...)

  for (x in parms) {
    cat(x)
  }
}
 > e="e"

 > niceplot(e)
e
