Append one dataframe to the end of another dataframe in R

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:
