Triangulation of Irregularly Spaced Data R package tripack version 1.3-9.4 CRAN Task View: NumericalMathematics (https://CRAN.R-project.org/view=NumericalMathematics) A constrained two-dimensional Delaunay triangulation package providing both triangulation and generation of voronoi mosaics of irregular spaced data. Please note that most of the functions are now also covered in package interp, which is a re-implementation from scratch under a free license based on a different triangulation algorithm.
