I don't think anyone has actually answered this. PPDE is a technical term, defined in
Friedman, Steutzle and Schroeder (1984) Projection pursuit density estimation. Journal of the American Statistical Association, 79(387):599-608, September 1984. I don't know of an R implementation, but have known of S ones (to which I no longer have access). If that is not what you mean by PPDE, please give us the reference(s) you have in mind.
