R help - Sep 2004 - drawing on axes

Hi,

I would like to make certain portions of axis lines thicker (as Tufte
suggests).  How can I draw on axes?  I only need a couple of line
segments on the left and bottom one.

Thanks

Tamas

How about:

plot (1, 1, xlim= c (-10, 10), bty= 'n')
axis (1, at= c (-10, -5), labels= FALSE, tick= T, lwd= 5, tck= 0)
axis (1, at= c (0, 3), labels= FALSE, tick= T, lwd= 5, tck= 0)
axis (2, at= c (0.8, 1), labels= FALSE, tick= T, lwd= 5, tck= 0)

Cheers, Lorenz
