Did you notice that the file generated from write.table() in R has missed a tab (\t) in the top-left corner, when row.names=T (by default)?
I found the solution here:
http://stackoverflow.com/questions/2478352/write-table-in-r-screws-up-header-when-has-rownames
write.table(“filename.xls”, sep=”\t”,
col.names = NA, row.names = TRUE)Actually, the R document has stated it clearly:
By default there is no column name for a column of row names. Ifcol.names = NAandrow.names = TRUEa blank column name is added, which is the convention used for CSV files to be read by spreadsheets.
