[R] Werid things when write.table

[Damian Abalo]

It works now. It is much more appropiate to add the titles than to add
a column with strings, and, in fact, it were rownames, not column
names (thats why colnames was set to true). Anyway using rownames
instead of adding an aditional column and setting row.names to true in
the write.trable works perfectly.
Thanks for the help, and sorry for asking such a basic thing, I am
still not very good at R :P
