\title{Create A Vector of Sequences}
\usage{
sequence(nvec)
}
\alias{sequence}
\arguments{
  \item{nvec}{an integer vector each element of which specifies the end
    point of a sequence.}
}
\description{
  For each element of \code{nvec} the sequence \code{seq(nvec[i])}
  is created.  These are concatenated and the result returned.
}
\details{
  Note that \code{sequence} works for 0 or negative inputs as
  \code{seq(x) == 1:x}.
