[R] expression() and plot title

[Bill.Venables at csiro.au]

Here is a suggestion you may care to develop

func <- function(a, b) {
	plot(1:10)
	title(main = bquote(a == .(a)*','~ b == .(b)))
	invisible()
}

try with

func(1,2)
func(36, 2^10) 
&c

Subject: [R] expression() and plot title

What I want to do is put the arguments I supply to a function  into the
title of a plot
Say I'm calling func.1
func.1(a=4,b=4)
plot(....,..., title("a=4, b=4"))
If I'm calling func.1 with different arguments, I want the plot title to
reflect that.
A small detail is that func.1 might have an argument with a default like
 c=a+b. I tried using expression but couldn't get it to work.

Is there a way to do this using expression() ?
