this files with this function).

\usage{
read.dataset(file.name, cy3 = 1, cy5 = 2, ids = 3, symdesc = NULL,
zscore = 4, type = 6, header = FALSE, sep = "\t")
}
\arguments{
\item{file.name}{a connection or a character string giving the
name of the file to read where each column represent the dataset components.}
\item{cy3}{column that represent Cy3.}
\item{cy5}{column that represent Cy5.}
\item{ids}{column that represent Id.}
\item{symdesc}{optional identifier besides Id column.}
\item{zscore}{column that represent the zscore value.}
\item{type}{column that represent if the experiment was performed as R
  vs I or M vs A.}
