title: 'GeomArchetypal: Finds the Geometrical Archetypal Analysis of a Data Frame'
version: 1.0.3
doi: 10.32614/CRAN.package.GeomArchetypal
abstract: Performs Geometrical Archetypal Analysis after creating Grid Archetypes
  which are the Cartesian Product of all minimum, maximum variable values. Since the
  archetypes are fixed now, we have the ability to compute the convex composition
  coefficients for all our available data points much faster by using the half part
  of Principal Convex Hull Archetypal method. Additionally we can decide to keep as
  archetypes the closer to the Grid Archetypes ones. Finally the number of archetypes
  is always 2 to the power of the dimension of our data points if we consider them
  as a vector space. Cutler, A., Breiman, L. (1994) <https://doi.org/10.1080/00401706.1994.10485840>.
