[R] Plotting colour-coded points
Hi, I have a file of the following type: idab 1 0.5 5 2 0.7 15 3 1.6 7 40.5 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?

Re: [R] Plotting colour-coded points
Hi Anjan,
Try something along the lines of
d$bb - with(d, cut(b, c(0,9,19,29)))
with(d, plot(a, id, col = bb, pch = 16, las = 1))
legend('topright', as.character(levels(d$bb)), col = 1:length(levels(d$bb)),
ncol = 3, pch = 16)
where 'd' is your original data.frame.
HTH,
Jorge
