pamr.to.excel(data,file,trace=TRUE)
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.
