%description
Provides an R interface for 'volesti' C++ package. 'volesti' computes
estimations of volume of polytopes given by (i) a set of points, (ii)
linear inequalities or (iii) Minkowski sum of segments (a.k.a. zonotopes).
There are three algorithms for volume estimation as well as algorithms for
sampling, rounding and rotating polytopes. Moreover, 'volesti' provides
algorithms for estimating copulas useful in computational finance. Methods
implemented in 'volesti' are described in A. Chalkis and V. Fisikopoulos
(2022) <doi:10.32614/RJ-2021-077> and references therein.
