listIndex(package, character.only = FALSE)
}
\arguments{
\item{package}{
a literal character string or a character string denoting the name
of a package.
}
\item{character.only}{
a logical indicating whether 'package' can be assumed to be
a character string.
}
}
\value{
for \code{listFunctions}, a character vector containing the names of
the exported functions in a package,
for \code{countFunctions}, a named numeric value giving the number of
the exported functions in a package.
\code{listIndex} doesn't return a useful value. It is used for the
