Subject: matplot(... panel.first=..) fails  <==> dealing with "..." (PR#267)
Message-ID: <199909060904.LAA12129@pubhealth.ku.dk>

Maybe, the following is not a bug in the strict sense,....

The following code shows what the effect :

  p1 <- function(...) plot.default(...)
  p2 <- function(...) { n <- names(list(...)); plot.default(...) }

  par(mfrow=c(2,2))
  p1(1:10, panel.first = grid(10,10)) # works okay (grid drawn)
  p2(1:10, panel.first = grid(10,10)) # doesn't draw the grid

A consequence of this is that the panel.first argument (of plot.default)
doesn't work with matplot()
	[well, matplot()'s doc doesn't claim it should, but still

-------
The real questions behind are:

1a) Why is "..." changed at the moment that I do  list(...)
1b) is this basic behavior desirable / changeable ....

2) How can one work around? 
   {save "..." to something else, first? 
    or explicitly save panel.first?}
