Is there a way to define a subsequent set of data.frame in R?

If I have a data.frame like this:

   X1 X2
1   1  A
2   2  A
3   3  B
4   4  B
5   5  A
6   6  A
7   7  B
8   8  B  
9   9  A
10 10  A

My goal is to define a set of data.frame as:

y1<-data[1:2,]
y2<-data[3:4,]
y3<-data[5:6,] ##...etc. by a loop.

Therefore, ideally I would like to use (for instance) a for loop

for (i in 1:5){
    y_i <- data[2*i:2*(i+1), ]
}

However, I cannot figure out how to define a subsequent set of data.frame such as y_i. Is there any method able to do this? Thanks in advance.

Solution

  • You can use assign. It will help you get the data frames you need with the naming convention you asked for.

    for (i in 1:5){
    assign(paste("y", i, sep="_"), data[(i*2-1):(i*2), ])
}
