\title{Extract of a Graft versus Host Disease monitoring experiment
  (Rizzieri et al., 2007)}
\description{
  A flow cytometry high throughput screening was used to identify
  biomarkers that would predict the development of GvHD. The GvHD dataset
  is an extract of a collection of weekly peripheral blood samples
  obtained from patients following allogenic blood and marrow
  transplant. Samples were taken at various time points before and after
  graft.

\usage{data(GvHD)}
\format{
  The format is an object of class \code{flowSet} composed of 35
  \code{flowFrames}.
  Each \code{flowFrame} corresponds to one sample at one time point.
  The \code{phenodata} lists:
  \describe{
  \item{Patient}{The patient Id code }
  \item{Visit}{The number of visits to the hospital}
  \item{Days}{The number of days since the graft. Negative values
    correpond to days before the graft.}
  \item{Grade}{Grade of the cancer}
}
}
\details{
  This GvHD dataset represents the measurements of one biomarker
  (leukocyte) for 5 patients over 7 visits  (7 time points). The blood
  samples were labeled with four different fluorescent probes to
  identify the  biomarker and the fluorescent intensity was determined
  for at least ten thousand cells per sample.
