Append one dataframe to the end of another dataframe in R (original) (raw)

Last Updated : 7 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:
