Trend and Spatial Pattern of Poverty in the Philippines

In a teaching demo that I have conducted, I discussed on how R can be used to analyze trends and spatial pattern of poverty incidence in the Philippines. Playing on the data I got from the National Statistical Coordination Board below is what I got.

Colored 3D Map

In my previous post, I showed how to make a 3D view of an area using the persp function. However, I felt this was not a complete representation, especially for digital elevation. While looking for some reference for my presentation on the use of R for data analysis and visualization, I came across a thread discussing " 3d plot with different levels done in different colors (solution)".  In this thread, a co-blogger Tamas K Papp's shared his levelpersp function. Using this function I tried to plot 3D view of Marinduque, Philippines using terrain and topo color.
