How to report automatically-generated argument values

["P.J.Wells" <P.J.Wells@open.ac.uk>]

I am developing the following function, the first few line of which
presently read:

Glick.test <- function(G.matrix, p.bar = NULL, ...){
        if(is.null(p.bar)) message.2 <- "internal"
                else message.2 <- deparse(substitute(p.bar))
        ....
}

(I need to create message.2 at the start, since -- as the code indicates --
p.bar (a vector) will be created internally if not supplied).

Originally I'd planned to supply p.bar manually, but it now turns out that I
want to make a number of calls to Glick.test using the following

for (i in 1:length(PRM.list))
        assign(paste(PRM.list[i], ".stats", sep=""),
                Glick.test(econ.matrix,
p.bar=eval(parse(text=grp.list[i]))))

where grp.list is a vector (I know...) of character strings naming the
appropriate p.bar objects.

As things stand, the current version of Glick.test() thus returns p.bar as
"eval(parse(text=grp.list[i]))".

Obviously I'd like it to report the names, but I can't hit on a convenient
strategy for this (naturally, I'm hoping to change the above, and the
objects it depends on, as little as possible).

Any suggestions?
