Hi all,

I am a new user of R. I just did my first real program.
I would like to know how to put a gradient (like rainbow() or topo.colors,
etc) to a* line* graph.


Instead of a red color, I would like to make it in rainbow colors.
Tried to do my own and tried searching but everywhere its about giving
gradient to point graph, not to a line graph. Please help, it is needed for
my work.

Thanks in advance
