Initialization Code

The following initialization code is actually doing A LOT under the hood. On top of starting R within your browser and importing the libraries specified in the code block, it also loads the elevation data for all of Tanzania, so that it can re-generate as many geospatial data realizations as you’d like (Click the “Run Code” button in the non-initialization cell below, to generate new realizations!)

Base R and ggplot2 Visualizations

Feel free to modify the code however you’d like, then click the “Run Code” button to generate and visualize new realizations of the geospatial process! (You can click “Start Over” to reset the code to its original state)
