\title{getLow, getUp functions of package distr}
\description{
getLow, getUp return lower and upper endpoint of a distribution ---
truncated to lower/upper \code{TruncQuantile} if infinite; in case of an object
of class \code{"LatticeDistribution"} with infinite lattice length, we search
for the smallest/largest point in the lattice which is returned by succesive
halving of \code{x=0.5} in \code{q(object)(x, lower.tail)} for \code{lower.tail}
\code{TRUE} resp. \code{false}.}
\usage{
\S4method{getUp}{AbscontDistribution}(object,
eps = getdistrOption("TruncQuantile"))
\S4method{getUp}{DiscreteDistribution}(object, ...)
\S4method{getUp}{LatticeDistribution}(object, ...)
\S4method{getUp}{UnivarLebDecDistribution}(object,
eps = getdistrOption("TruncQuantile"))
\S4method{getUp}{UnivarMixingDistribution}(object,
eps = getdistrOption("TruncQuantile"))
\S4method{getLow}{AbscontDistribution}(object,
eps = getdistrOption("TruncQuantile"))
\S4method{getLow}{DiscreteDistribution}(object, ...)
\S4method{getLow}{LatticeDistribution}(object, ...)
\S4method{getLow}{UnivarLebDecDistribution}(object,
eps = getdistrOption("TruncQuantile"))
\S4method{getLow}{UnivarMixingDistribution}(object,
eps = getdistrOption("TruncQuantile"))
}
\arguments{
\item{object}{a distribution object}
\item{eps}{truncation point (numeric)}
\item{\dots}{for convenience only; makes it possible to call \code{getLow},
\code{getUp} with argument \code{eps} no matter of the class of \code{object};
is ignored in these functions.}
}
\value{
\item{getLow,getUp}{a \code{numeric} of length 1}
}
