    genenames- a vector of gene names. Optional components: samplelabels and
    batchlabels, both character vectors}

\details{
  \code{pamr.to.excel}
    writes out the data object into a tab-delimited text file, of the same
    form as is read in by pamr.from.excel.
    Useful for writing out data that has been imputed by pamr.knnimpute or
    adjusted by pamr.batchadjust. Note- this function writes the file out
    one line at a time, and hence can take a while for big datasets.
