VecLat-class {pgs} | R Documentation |
Objects of class "VecLat"
represent vector lattices.
Objects can be created by calls of the form new("VecLat", ...)
or
using generators such as VecLat
, RectLat2
, HexLat2
.
dimspace

. Dimension
of the space where the lattice lies.dimsupp

. Dimension
of the support of the lattice, defined as the smallest vector
subspace containing the lattice.gmat
