Hi,
I am using the plot function to make a simple plot of my data with one
variable against another and want to colour the data points according
to a third variable. The third variable is continuous (Time) and I
want to try two different ways of colouring the data points, either:
Divide time it into three groups and then colour each data point
accordingly eg. 30-60 minutes in green, 60-90 minutes in red and
90-120 minutes in blue..
or,
Colour the data points using a colour gradient eg. with increasing
colour intensity as time increases..
I think I need to be able to do it within the plot() function as I
have lines fitted from a model which I will also add to the graph.
Any suggestions would be greatly appreciated??
Thanks in advance
Anna
