If it really is an R matrix, you should either look up `write.matrix` or perhaps more simply wrap as.data.frame(.) around that object.

write.foreign specifies that its first argument be a dataframe.

There are arguments in write.table and its cvs wrappers to suppress column names. Please read this more carefully:

?write.table
