Re: [Rd] write.csv

I don't understand very well if your problem is rownames or column names, but what you want must be :
row.names=FALSE and/or col.names=FALSE, which are arguments of the function 'write.table()'

don't think you need to load any particular package for that.

see also :

'write.csv' and 'write.csv2' provide convenience wrappers for
     writing CSV files.  They set 'sep', 'dec' and 'qmethod', and
     'col.names' to 'NA' if 'row.names = TRUE' and 'TRUE' otherwise.
from ?write.table

hope this helps.
