Back-end connections to 'LattE' (<https://www.math.ucdavis.edu/~latte/>) 
	for counting lattice points and integration inside convex polytopes and 
	'4ti2' (<http://www.4ti2.de/>) for algebraic, geometric, and combinatorial 
	problems on linear spaces and front-end tools facilitating their use in the 
	'R' ecosystem.

A powerful and elegant high-level data visualization
  system inspired by Trellis graphics, with an emphasis on
  multivariate data. Lattice is sufficient for typical graphics needs,
  and is also flexible enough to handle most nonstandard requirements.
  See ?Lattice for an introduction.

Functions that compute the
  lattice-based density and regression estimators for two-dimensional regions
  with irregular boundaries and holes.  The density estimation technique is 
  described in Barry and McIntyre (2011) 
  <doi:10.1016/j.ecolmodel.2011.02.016>,
  while the non-parametric regression technique is described in McIntyre and
  Barry (2018)  <doi:10.1080/10618600.2017.1375935>.
