Pptreeviz: An R package for visualizing projection pursuit classification trees

Research output: Contribution to journalArticlepeer-review

7 Scopus citations


PPtreeViz, an R package, was developed to explore projection pursuit methods for classification. It provides functions to calculate various projection pursuit indices for classification and to explore the results in the space of projection. It also provides functions for the projection pursuit classification tree. The visualization methods of the tree structure and the features of each node in PPtreeViz can be used to easily explore the projection pursuit classification tree structure and determine the characteristics of each class. To calculate the projection pursuit indices and optimize these indices, we use the Rcpp and RcppArmadillo packages in R to improve the speed.
