How to add a row to R dataframe ?

Last Updated : 29 Dec, 2022

In this article, we will see how to add rows to a DataFrame in R Programming Language. To do this we will use rbind() function. This function in R Language is used to combine specified Vector, Matrix or Data Frame by rows.

Syntax:

rbind(dataframe 1, dataframe 2)

Example 1 :

R

# creating a data frame with some data
df9 = data.frame(id=c(1,2,3),
                 name=c("karthik","bhagiradh","kethan")) 

print("Original data frame")

# printing the data frame 
print(df9) 

# declaring a row of values in 
# data.frame() function
df8 = data.frame(4,"shyam") 

# adding names to the row values
names(df8)=c("id","name")

# passing the original data frame and new 
# data frame into the rbind() function
df7=rbind(df9,df8)  

print("data frame after adding a new row")
print(df7)

Output :

Example 2 :

Python3

# creating a data frame with some data
df = data.frame(id=c(1,2,3),
                name=c("maruti suzuki","tata","ford")) 

print("Original data frame")
print(df) 

# declaring a row of values in
# data.frame() function
df1 = data.frame(4,"volkswagen")

# adding names to the row values
names(df1)=c("id","name") 

# passing the original data frame and 
# new data frame into the rbind() function 
df2=rbind(df,df1) 

print("data frame after adding a new row")
print(df2)

Output :

Example 3:

R

# creating a data frame with some data
df3 = data.frame(id=c(1,2,3),
                 name=c("Asus","HP","Acer")) 

print("Original data frame")
print(df3) 

# declaring a row of values in 
# data.frame() function
df4 = data.frame(4,"Dell")

# adding names to the row values
names(df4)=c("id","name") 

# passing the original data frame and 
# new data frame into the rbind() function
df5=rbind(df3,df4) 

print("data frame after adding a new row")
print(df5)
