Hello, I am facing a problem in drawing heat map using R. I have a 70X3 matrix and I want to draw a heat map with 1 coloumn on X axis another on Y axis and want to show the value of 3rd coloumn using heat colours. Could you please help me with this . Thank you . Regards, Sumit [[alternative HTML version deleted]]

Look at the "image" function and the "levelplot" function in
the lattice package.

Hello,
I am facing a problem in drawing heat map using R.
I have a 70X3 matrix and I want to draw a heat map with 1 coloumn on X axis
another on Y axis and want to show the value of 3rd coloumn using heat
colours.
Could you please help me with this .
Thank you .

Hii The contour plot is somewhat similar to what I want. I am attaching the data here. What I want to do is divide all the three variable( Recency, frequency,and monetory ) in 5 intervals based on their values.That will make 25 rectangle(5(recency)X 5(frequency) boxes on heat plot. and then plot a heat map with recency on X axis and frquency on Y axis, and also I want to show the no. of elements in each box( total 25) by heat colours i.e increasing no. of elements with the darker colour box. And one more plot with the same variable on XY as mentioned above but this time box colour depicting the average monetary value of that box. Hope this clears the problem I am facing. Thank you.
