Hi, I have a file of the following type: id a b 1 0.5 5 2 0.7 15 3 1.6 7 4 0.5 25 ....................
I would like to plot the data in column a on the y-axis and the corresponding data in column id on the x-axis, so plot(a~id). However I would like to colour these points according to the data in column b. column b data may be colour coded into the following bins: 0-9; 10-19; 20-29. Any idea on how to accomplish this?
