I would like to know how to put a gradient (like rainbow() or topo.colors, etc) to a* line* graph. Example: ar1=array(data=1:10,dim=9) ar2=array(data=11:20,dim=9) plot(ar1,ar2,type="l",col="red",lwd=3) 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
