Hi, The first line has less elements than the rest of 'rownames_colnames.write.table.xls'. I am wondering if there is a way to print an additional '\t' at the beginning of the first line.
$ Rscript write.table.R > x=matrix(1:20,nc=2) > rownames(x)=letters[1:10] > colnames(x)=letters[1:2] > write.table(x,"rownames_colnames.write.table.xls",sep='\t') > $ cat rownames_colnames.write.table.xls "a" "b" "a" 1 11 "b" 2 12 "c" 3 13 "d" 4 14 "e" 5 15 "f" 6 16 "g" 7 17 "h" 8 18 "i" 9 19 "j" 10 20 Regards, Peng ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
