write.dataSet(dataSet.spot, fileName, quote
= FALSE, col.names = FALSE, row.names = FALSE,
Zscore.min = NULL, Zscore.max = NULL, sep = "\t")
\item{dataSet.spot}{An object of DataSet class}
\item{fileName}{The name of the output file where the data will be

\item{quote}{If quote = TRUE, all values in the file will be quoted.}

\item{row.names}{If row.names = TRUE will be an extra column that
  numerates every rows in the file.}
\item{Zscore.min}{The lower value in a range, if Zscore.min = NULL then
  the file will contain all values bellow Zscore.max}
\item{Zscore.max}{The greater value in a range, if Zscore.max = NULL
  then file will be contain all values above Zscore.min. Both values,
  Zscore.min and Zscore.max can not be NULL}
\item{sep}{Character to separate the columns in file. By default sep
  = "\\t".}
