Creating Chernoff faces in R

One of the alternative methods to visualize multivariate data is using Chernoff faces. Each variable in the dataset is used to represent a feature of the face.

Kosara (http://eagereyes.org/criticism/chernoff-faces) discusses the limitation of using Chernoff faces at length.

In order to construct Chernoff faces, I have downloaded some specific macroeconomic variables for a set of countries from the World Bank website.
