How to add rows in an R data frame?

To add rows in an R data frame, we can follow the below steps −

• First of all, create a data frame.

• Then, use rbind function and the vectors that will be added as rows to the data frame.

Example

Create the data frame

Let’s create a data frame as shown below −

x<-rpois(25,5) y<-rpois(25,2) df<-data.frame(x,y) df

Output

On executing, the above script generates the below output(this output will vary on your system due to randomization) −

 x y 1 9 3 2 4 1 3 5 0 4 8 1 5 5 2 6 6 3 7 7 2 8 3 4 9 5 1 10 2 2 11 5 2 12 2 2 13 8 2 14 12 4 15 7 4 16 3 2 17 4 0 18 8 2 19 6 1 20 2 4 21 3 1 22 4 1 23 4 1 24 4 3 25 2 2

Add rows in the data frame

Using rbind function and the vectors to add rows in the data frame as shown below −

x<-rpois(25,5) y<-rpois(25,2) df<-data.frame(x,y) df<-rbind(df,c(5,5),c(2,1),c(0,1),c(5,4),c(3,6)) df

Output

 x y 1 9 3 2 4 1 3 5 0 4 8 1 5 5 2 6 6 3 7 7 2 8 3 4 9 5 1 10 2 2 11 5 2 12 2 2 13 8 2 14 12 4 15 7 4 16 3 2 17 4 0 18 8 2 19 6 1 20 2 4 21 3 1 22 4 1 23 4 1 24 4 3 25 2 2 26 5 5 27 2 1 28 0 1 29 5 4 30 3 6
