For some clever reason, write.csv won't let you set col.names argument to
FALSE, but you can use it with write.table using sep=",".

A self-contained, minimal, and working example:

write.csv(matrix(1:10,2,5), "test.csv")
write.table(matrix(11:20,2,5), "test.csv", sep=",", append=TRUE,
col.names=FALSE)

KK
