## Creating a three-dimensional heat map and a stereo map

We have studied two-dimensional heat maps, but R also allows us to plot three-dimensional interactive heat maps using the `NeatMap`

package. The `NeatMap`

package manual states the limitation of using the `heatmap()`

function as "*The traditional clustered heatmap makes use of cluster analysis to re-order rows and columns such that similar elements are placed together. However, cluster analysis is a poor choice for ordering method since this does not provide a unique ordering"*.

### Getting ready

In order to plot a three-dimensional heat map and a stereo map, we would need to install the `NeatMap`

package available in R.

### How to do it…

In order to plot a three-dimensional heat map and a stereo map, we would start by loading the `NeatMap`

package and load the data. After loading and cleaning the data, we would use `make.profileplot3D()`

and `make.stere.profileplot3D`

to plot three-dimensional heat maps and stereo maps, respectively:
