[R] problem with mfg argument of par

[Ken Knoblauch]

I'm having a problem with the mfg option of par.  Am I making an error in my
usage?  Here is a simple example that I thought would plot to the 4 corners
of a 2x2 plot but doesn't plot to the lower right and plots twice on the
upper left.

par(mfrow = c(2, 2))
pos <- 	as.matrix(expand.grid(1:2, 1:2))
for (ix in 4:1) {
	par(mfg = pos[ix, ])
	plot(1:5)
	}

Thank you in advance.
