\title{Lists of Atomic Vectors in Natural and Rle Form}
\description{An extension of \code{\linkS4class{Sequence}} that holds
  only atomic vectors in either a natural or run-length encoded form.}

\details{
  The lists of atomic vectors are \code{LogicalList}, \code{IntegerList},
  \code{NumericList}, \code{ComplexList}, \code{CharacterList}, and
  \code{RawList}. There is also an \code{RleList} class for
  run-length encoded versions of these atomic vector types.

  Each of the above mentioned classes is virtual with Compressed* and Simple*
  non-virtual representations.

}

\section{Group Generics}{
  AtomicList objects have support for S4 group generic functionality to operate
  within elements across objects:
  \describe{
    \item{\code{Arith}}{\code{"+"}, \code{"-"}, \code{"*"}, \code{"^"},
      \code{"\%\%"}, \code{"\%/\%"}, \code{"/"}}
    \item{\code{Compare}}{\code{"=="}, \code{">"}, \code{"<"}, \code{"!="}, 
      \code{"<="}, \code{">="}}
    \item{\code{Logic}}{\code{"&"}, \code{"|"}}
    \item{\code{Ops}}{\code{"Arith"}, \code{"Compare"}, \code{"Logic"}}
    \item{\code{Math}}{\code{"abs"}, \code{"sign"}, \code{"sqrt"},
      \code{"ceiling"}, \code{"floor"}, \code{"trunc"}, \code{"cummax"},
      \code{"cummin"}, \code{"cumprod"}, \code{"cumsum"}, \code{"log"},
      \code{"log10"}, \code{"log2"}, \code{"log1p"}, \code{"acos"},
      \code{"acosh"}, \code{"asin"}, \code{"asinh"}, \code{"atan"},
      \code{"atanh"}, \code{"exp"}, \code{"expm1"}, \code{"cos"},
      \code{"cosh"}, \code{"sin"}, \code{"sinh"}, \code{"tan"}, \code{"tanh"},
      \code{"gamma"}, \code{"lgamma"}, \code{"digamma"}, \code{"trigamma"}}
    \item{\code{Math2}}{\code{"round"}, \code{"signif"}}
    \item{\code{Summary}}{\code{"max"}, \code{"min"}, \code{"range"},
      \code{"prod"}, \code{"sum"}, \code{"any"}, \code{"all"}}
    \item{\code{Complex}}{\code{"Arg"}, \code{"Conj"}, \code{"Im"},
      \code{"Mod"}, \code{"Re"}}
  }
  See \link[methods]{S4groupGeneric} for more details.
}

\section{Other Basic Methods}{
  The AtomicList objects also support a large number of basic methods.
  Like the group generics above, these methods perform the corresponding
  operation on each element of the list separately. The methods are: 

  \describe{
    \item{General}{\code{\%in\%}, \code{is.na}, \code{match}, \code{sort},
                   \code{table}, \code{unique}}
    \item{Logical}{\code{!}, \code{which}}
    \item{Numeric}{\code{diff},
                   \code{pmax}, \code{pmax.int}, \code{pmin}, \code{pmin.int},
                   \code{mean}, \code{var}, \code{cov}, \code{cor}, \code{sd},
                   \code{median}, \code{quantile}, \code{mad}, \code{IQR}}
    \item{Running Window}{\code{smoothEnds}, \code{runmed}. \code{runmean},
                          \code{runsum}, \code{runwtsum}, \code{runq}}
    \item{Character}{\code{nchar}, \code{chartr}, \code{tolower},
                     \code{toupper}, \code{sub}, \code{gsub}}
  }
}
