Plot: Two newbie questions

Hi!

I would like to

1) Put a title on a page with several plots (aligned witn mfrow=(x,y)).

use mtext

2) Turn the y axis upside down, ie high values at the bottom, large ones
at the top.

Try

plot(x, -y, axes=FALSE)
axis(1)
axis(2)

[...]

or wait til Peter D gives a much more cunning method

Cheers
