\usage{
rlepack(x, ...)
\method{rlepack}{integer}(x, pack = TRUE, ...)
rleunpack(x)
\method{rleunpack}{rlepack}(x)
\method{rev}{rlepack}(x)
\method{unique}{rlepack}(x, incomparables = FALSE, ...)
\method{anyDuplicated}{rlepack}(x, incomparables = FALSE, ...)
}
\arguments{
\item{x}{in 'rlepack' an integer vector, in the other functions an object of
class 'rlepack'}
\item{\dots}{just to keep R CMD CHECK quiet (not used)}
\item{pack}{FALSE to suppress packing}
\item{incomparables}{just to keep R CMD CHECK quiet (not used)}
}
\value{
A list with components \item{ first }{ the first element of the
packed sequence } \item{ dat }{ either an object of class \code{\link{rle}}
or the complete input vector \code{x} if rle-packing is not efficient }
\item{ last }{ the last element of the packed sequence }
}
\description{
Basic utilities for rle packing and unpacking and apropriate methods for
\code{\link{rev}} and \code{\link{unique}}.
