The help pages (here for bquote) are your friend.
I don't think you really want to do this via do.call(), as you want some
arguments evaluated and some unevaluated. Rather, match.call(), alter it
as you want, and then eval.parent it. Something like
ploteps <- function(file, plotFunction, ..
Try this:
f <- function(cmd, ...) {
cat("Hello\n")
mc <- match.call()
mc <- mc[-1]
eval.parent(mc)
cat("Goodbye\n")
}
f(plot, 1:10)

I'm trying to write a simple wrapper for plotting functions to make
them print to postscript, something like
ploteps <- function(file, plotFunction, ...) {
args <- list(bquote(...))
# prepare postscript device
do.call(plot, args)
# close postscript device
}
I have inserted the bquote
