Hi, An other possibility might be to use two devices and use dev.set to go from one to another :
x11() # the first device (may be windows() or quartz() depending on you OS) plot(1,1, col="blue") # blue plot x11() # the second plot(1.2,1.2, col="red") # red plot points(1.1,1.1) # appears to bottom left of red point dev.set(dev.prev()) # switch plots points(1.1,1.1) Le 23.05.2006 17:54, Yan Wong a écrit : > On 23 May 2006, at 15:57, Greg Snow wrote: > > >> The best thing to do is to create the first plot, add everything to >> the >> first plot that you need to, then go on to the 2nd plot, etc. >> > > Yes, I realise that.
