\title{Get lower / upper bounds and allowed discrete values for parameters.}
\usage{
getLower(obj, with.nr = FALSE, dict = NULL)
getUpper(obj, with.nr = FALSE, dict = NULL)
getValues(obj, dict = NULL)
}
\arguments{
\item{obj}{(\code{\link[=Param]{Param()}} | \code{\link[=ParamSet]{ParamSet()}} | \code{list})\cr
Parameter, parameter set or list of parameters, whose boundaries and/or
values should be extracted. In case the boundaries or values contain
expressions, they will be evaluated using the provided dictionary \code{dict}.}
\item{with.nr}{(\code{logical(1)})\cr
Should number from 1 to length be appended to names of vector params?
Default is \code{FALSE}.}
\item{dict}{(\code{environment} | \link{list} | \code{NULL})\cr
Environment or list which will be used for evaluating the variables of
expressions within a parameter, parameter set or list of parameters. The
default is \code{NULL}.}
}
\value{
\code{vector} | \code{list}. Named by parameter ids.
}
\description{
\code{getLower} and \code{getUpper} return a numerical vector of lower and
upper bounds, \code{getValues} returns a list of possible value sets for discrete
parameters.
Parameters for which such bound make no sense - due to their type - are not
present in the result.
}
