write.csv with append = TRUE

write.table() should append just fine. write.csv() doesn't append I'm told because there's no guarantee it matches the column headings of the original file. That said, write.table(..., append = TRUE, sep = ",") is a pretty good approximation.
You may also want dec="." and qmethod="double". I forget if the row name defaults are equal... Duncan Murdoch

Is there a way to make any of the write functions (.table or .csv) append to the same file? I get this warning message and do not know how to enable the appending. Warning messages: 1: In write.csv(names(Lbys)[c], fo, append = TRUE) : attempt to set 'append' ignored 2: In write.csv(Lbys[[c]], fo, append = TRUE) : attempt to set 'append' ignored Regards, Alex van der Spek
