write to file append by column

Readers,

Scenario: data x consists of one column;
1
2
3

data y;
4
5
6

Is it possible to write to file such that the file is:
1,4
2,5
3,6

using the write.file function? I have tried the command:

write(x,file="file.csv",ncolumns=1,append=TRUE,sep=",")
write(y,file="file.csv",ncolumns=1,append=TRUE,sep=",")

but the result is:

1
2
3
4
5
6

yours,
