Hi Sarah,
To me, the heatmap function calculates "density value" for each grid
of the heatmap automatically from the input matrix. In my case, I
already got the "density value" as a vector, say Z. I want to plot a
heat map with x and y as is axsis and z values as the "density" of
grid. I am not familiar with R code, so I am writting to ask how to.
Thanks!

You mean like the examples in help("heatmap") ?

Hi everyone,
I have three numerica vectors: x, y, z. I want to plot a heatmap or surface
plot of z against x and y. Is there any package for this? If possible,
please drop me several lines of example code. Thanks!
