Hi
Just one of those niggles.......
I've just been trying to plot a filled circle.
I thought that this would do it
plot(1,1,type="n")
points(1,1,pch=1,bg="blue",cex=5)
#bg: background ("fill") color for open plot symbols
But I need to do this instead
points(1.2,1,pch=19,col="blue",cex=5)
Am I misunderstanding the "bg" option in the points function?

The quick answer is: example(points). I think you'll get the point. -- O__ ---- Peter Dalgaard ??ster Farimagsgade 5, Entr.B c/ /'_ --- Dept. of Biostatistics PO Box 2099, 1014 Cph.

See the examples. pch=1 is not an `open plot symbol': 21-25 are. So in your case points(1.3, 1, pch=21, col="blue", bg="red", cex=5) may be illuminating. -- Brian D.
