Object of class "DiscreteDistribution"
numeric vector with data.

normally not set by the user: whether the lower.tail=FALSE

we make particular use of a logarithmic representation to enhance accuracy.
controls whether in generating a new discrete
distribution, support points closer together than .DistrResolution
are
collapsed.
controls whether there is a warning
whenever collapsing occurs or when two points are collapsed by a call to
unique()
(default behaviour if .DistrCollapse
is FALSE
)
minimal spacing between two mass points in a discrete distribution
you may help R in calculations if you tell it whether
the distribution is non-symmetric (default) or symmetric with respect
to a center; in this case use Symmetry=SphericalSymmetry(center)

The function is a simple utility function providing a wrapper to the
generating function DiscreteDistribution
.
Typical usage is
EmpiricalDistribution(data)
DiscreteDistribution
DiscreteDistribution-class
x <- rnorm(20)
D1 <- EmpiricalDistribution(data = x)
D1
plot(D1)
