Combine Vectors, Matrix or Data Frames by Rows in R Language – rbind() Function
In this article, we will discuss how we Combine Vectors, Matrices, or Data Frames by Rows in R Programming Language using rbind function.
What is rbind function?
The rbind
function combines or concatenates data frames or matrices by rows. the rbind stands for row binds it shows that it appends rows of one object to another.
Syntax:
rbind(x1, x2, …, deparse.level = 1)
Parameters:x1, x2: vector, matrix, data frames
deparse.level: This value determines how the column names are generated. The default value of deparse.level is 1.
Combine Vectors using rbind() Function
We will create two vectors and combine them with the help of rbinf function.
R
# R program to illustrate # rbind function # Initializing two vectors x <- 2:7 y <- c (2, 5) # print the value of x x # print the value of y y # Calling rbind() function rbind (x, y) |
Output:
[1] 2 3 4 5 6 7
[1] 2 5
[,1] [,2] [,3] [,4] [,5] [,6]
x 2 3 4 5 6 7
y 2 5 2 5 2 5
Combine Matrix using rbind() Function
We will create two matrix and combine them with the help of rbinf function.
R
# create one matrix a1<- matrix (1:9,3,3) a1 # Create second matrix a2<- matrix (10:18,3,3) a2 # combine the both metrix rbind (a1,a2) |
Output:
[,1] [,2] [,3]
[1,] 1 4 7
[2,] 2 5 8
[3,] 3 6 9
[,1] [,2] [,3]
[1,] 10 13 16
[2,] 11 14 17
[3,] 12 15 18
[,1] [,2] [,3]
[1,] 1 4 7
[2,] 2 5 8
[3,] 3 6 9
[4,] 10 13 16
[5,] 11 14 17
[6,] 12 15 18
Combine data frame using rbind() Function
We will create two data frame and combine them with the help of rbinf function.
R
# Create the first data frame df1 <- data.frame ( Name = c ( "Anurag" , "Nishant" , "Jayesh" ), Age = c (25, 30, 22), Score = c (90, 85, 92) ) df1 # Create the second data frame df2 <- data.frame ( Name = c ( "Vipul" , "Shivang" , "Pratham" ), Age = c (28, 35, 27), Score = c (88, 91, 89) ) df2 # Combine the data frames by rows combined_df <- rbind (df1, df2) # Display the result print (combined_df) |
Output:
Name Age Score
1 Anurag 25 90
2 Nishant 30 85
3 Jayesh 22 92
Name Age Score
1 Vipul 28 88
2 Shivang 35 91
3 Pratham 27 89
Name Age Score
1 Anurag 25 90
2 Nishant 30 85
3 Jayesh 22 92
4 Vipul 28 88
5 Shivang 35 91
6 Pratham 27 89
Combine data frame having missing values
We will create two data frames having missing values and combine them with the help of rbinf function.
R
# Create the first data frame df1 <- data.frame ( Name = c ( "Anurag" , "Nishant" , "Jayesh" ), Age = c (25, NA , 22), Score = c (90, 85, NA ) ) df1 # Create the second data frame df2 <- data.frame ( Name = c ( "Vipul" , "Shivang" , "Pratham" ), Age = c ( NA , 35, 27), Score = c (88, NA , 89) ) df2 # Combine the data frames by rows combined_df <- rbind (df1, df2) # Display the result print (combined_df) |
Output:
Name Age Score
1 Anurag 25 90
2 Nishant NA 85
3 Jayesh 22 NA
Name Age Score
1 Vipul NA 88
2 Shivang 35 NA
3 Pratham 27 89
Name Age Score
1 Anurag 25 90
2 Nishant NA 85
3 Jayesh 22 NA
4 Vipul NA 88
5 Shivang 35 NA
6 Pratham 27 89
Here are the some of the examples for Combine Vectors, Matrix or Data Frames by Rows in R Programming Language. for combining rows it is necessary that it contain same amount of columns.
