ggplot: colours to geom_segments
Just as an exercise I am tying to add colours to a geom_segment command. I can get one colour but not a sequence of colours.
Can anyone suggest how I can get the green lines in the plot below to be different colours? I thought I could use a palatte of colours but that did not seem to work.
Thanks

2d plotting and colours
...x, i, 20)
plot(x, col = cl$cluster)
points(cl$centers, col = 1:i )
I see that there are only 8 colours defined , namely
black,red,green,blue,cyan,magenta,yello,gray.
How should i set my colour preferences to obtain my palette of colours? I
checked in the totorial which talks about R.colors and palatte , but i
failed to understand how to set it.
Thank You
