container for hg18 annotation

\end{Description}
\begin{Section}{Objects from the Class}
Objects can be created by calls of the form \code{new("hg18track", assayData, featureData, experimentData, annotation, dataVals, ...)}.
These are single-sample eSet instances.

Note that \code{demoTrk19} is a restriction of the \code{rawCD4} structure
to the interval of chromosome 19 that was assayed in the ENCODE project for DnaseI hypersensitivity.

\begin{Section}{Methods}
\describe{
\item[[] \code{signature(x = "hg18track")}: select using
numeric, logical, or chrnum indices. 
\item[chrnum] \code{signature(object = "hg18track")}: extract
numeric tokens for chromosome number at which data values are
obtained; note that chrnum is also used as name of
a class.
\item[dataVals] \code{signature(object = "hg18track")}: actual
data values 
\item[getTrkXY] \code{signature(object = "hg18track", type = "character")}: obtain a list with components x, y indicating location and
data value respectively; location is within chromosome; default type
is 'midpoint' of locations given as intervals 
\item[getTrkXY] \code{signature(object = "hg18track", type = "missing")}: 
take default midpoint x values corresponding to data values 
\item[rangeLocs] \code{signature(object = "hg18track")}: if measures from
only one chromosome are present , this returns low and high values of chromStart
and chromEnd respectively, otherwise error.
\item[clip] \code{signature(obj = "hg18track",
         low="numeric", hi="numeric", attr="ANY")}: create a restriction
of the track using an interval specification.  by default
the \code{chromStart} featureData component is used for
coordinates to clip; if \code{attr} is non-missing, the
featureData component named by \code{attr} will be used.
\item[initialize] \code{signature(.Object = "hg18track")}: create
a new instance
