Crafting an interactive globe using plotly
Until now, this chapter explored several core points related to mapping. We saw how maps can deliver important information, how paths, polygons, and points can be used to draw maps, how to read shapefiles using nothing but R, and how to set projection types and scales.
Now we will explore the advantages of having interactive maps. Even more than that, the advantages of having interactive globes. This recipe will make a globe that you can spin at will, and it does not request shapefiles at all, though they can be used if needed.
For this particular recipe, we'll be using the plotly
package to map countries affected by the 2009 banking crisis. On this course, the recipe will introduce you to a whole new way of mapping using plotly
. Data here is a little different; we will be looking for some columns names instead of actually data frame observations. Now for the requirements.

Data comes from the Ecdat
package--you know the drill:
