Append one dataframe to the end of another dataframe in R
  • Last Updated : 07 Apr, 2021

In this article, we are going to append the data frame to another data frame using “$” operator in R Programming Language.

Approach

  • Create vectors
  • Create one dataframe (dataframe1) by passing these vectors
  • Create another dataframe (dataframe2)by passing these vectors
  • Finally, append the dataframe2 to dataframe1 using” $” operator.
  • Display resultant dataframe

$ operator is used to add dataframe as a column.

Syntax: dataframe_one$column_name=dataframe_two

Parameters:



  • column_name is the name of the new column
  • dataframe_two is the dataframe 2 that is appended
  • dataframe_one is the first dataframe.

Let us break the problem down into smaller clusters and make it is to understand, Let us first create two dataframes independently. 

R




# creating vectors for dataframe 1
names=c("bobby","sravan","ojaswi")
age=c(20,22,16)
  
# creating vectors for dataframe 2
address=c("kakumanu","kakumanu","hyderabad")
marks=c(89,98,90)
  
# pass these vectors to data frame1 a
a=data.frame(names,age)
  
# pass these vectors to data frame2 b
b=data.frame(address,marks)
print(a)
print(b)

Output:

After, two dataframes have been created let us append one into another.

R




# creating vectors for dataframe 1
names=c("bobby","sravan","ojaswi")
age=c(20,22,16)
  
# creating vectors for dataframe 2
address=c("kakumanu","kakumanu","hyderabad")
marks=c(89,98,90)
  
# pass these vectors to data frame1 a
a=data.frame(names,age)
  
# pass these vectors to data frame2 b
b=data.frame(address,marks)
  
print(a)
print(b)
print("-------'")
print("appending dataframe 2 to data frame1")
  
# appending using $ operator
a$other_details=b
print(a)

Output:
