An R package implementing a Projection Pursuit (PP) algorithm based on finite Gaussian Mixture Models (GMMs) for density estimation using Genetic Algorithms (GAs) to maximise an approximated negentropy index. The ppgmmga algorithm provides a method to visualise high-dimensional data in a lower-dimensional space.
