Description Details Objects from the Class Slots Methods See Also

Objects of class `"FigLat"`

represent lattices of
figures of the form *Lambda+L+F*, where
*Lambda* is a (translation) vector lattice, *L* is a
vector subpace (may be reduced to the null vector) and *F* is a
bounded figure.

The vector subspace *L* should be
perpendicular to the support of the vector lattice
*Lambda* and to the figure *F*.

Objects can be created by calls of the form `new("FigLat", ...)`

or
using generators such as `FigLat`

.

for a FigLat object.- plot
`signature(x = "FigLat", y = "missing")`

: plot a FigLat object. Implemented only for planar figures of lattices. The arguments`xlim`

and`ylim`

are mandatory in order to define the plot region. If the extra argument`add`

(default:`FALSE`

) is`TRUE`

, the lattice of figures is added to the current plot.`signature(x = "FigLat")`

: print a FigLat object.- scaling
`signature(x = "FigLat", s = "numeric")`

:`scaling`
