Duncan,
Thanks you - your deparse(substitute(...)) work - fantastic.
But, when I pass in multiple arguments: f(z[,1],z[,2])
I only show first argument, rest shows up as NULL
Yes, that's because substitute has specific meanings for its two
arguments

what about:
niceplot<-function(...) {
arg.names <- as.list (match.call () [-1])
for (a in seq_along (arg.names))
cat (as.character (as.expression (arg.names [[a]])), "\n\n")
}
niceplot (greeneye, log (greeneye), 1:3)
note that this works also if there is no "greeneye"

David,
That's useful to highlight my problem.
If instead of e="e" we use a vector like GreenEyes:
> GreenEyes=c(1,2,3,4)
> niceplot(GreenEyes)
1 2 3 4

What I want is niceplot to print "GreenEyes" bot 1 2 3 4
I want this so I can use it in a legend without having to type in
"GreenEyes"...

I think you need to provide a richer example:
niceplot<-function(...) {
parms=list(...)
for (x in parms) {
cat(x)
}
}
