Quick question!

Just a further quick question:

If I have this:

for(i in 1:n) {
 subset <- data[which(data$id==i),]

which returns the rows where I have the variable ID=1,
how can I tell the same statement to return just
column Y where ID=i?

The subset() function does this:

        For(i in 1:n) {
                ss <- subset(data, id == i, Y)
                }
