**cbind()** function and **data.frame()** function in the base R package is used to combine two vectors in R. Vectors in R hold the multiple values of the same data type. Functions take vectors as input parameters and combine two vectors to data frame or matrix in R.

**cbind()** function of base R package takes the sequence of vectors and combines them by columns.

```
cbind() syntax:
cbind(..., deparse.level = 1)
Where,
... = vectors or matrices.
```

**data.frame()** function of base R package is used to create r data frames. It is used as a data structure as it has many properties of matrices or lists.

```
data.frame() syntax:
data.frame(..., row.names = NULL, check.rows = FALSE,
check.names = TRUE, fix.empty.names = TRUE,
stringsAsFactors = FALSE)
```

In this tutorial, we will discuss how to combine two vectors in R using cbind() and data.frame() function.

## Combine Two Vectors in R to Matrix

Using the **cbind()** function of the base R package, we can combine two vectors to the matrix. cbind() function takes a sequence of vectors as input parameters.

Let’s practice with an example for combining vectors in R.

Use c() function to create vectors in R. In the below example, **name** vector contains multiple values of string data type and **age** vector contains multiple values of integer type.

```
name = c("Tom","Kim","Sam","Julie","Emily","Chris")
age <- c(18, 20, 17, 21)
```

Use the **cbind()** function for combining two vectors in R into a matrix. **name** and **age** vectors are passed as arguments in the cbind() function.

```
# Concetenate two vectors in R into a matrix
student_info <- cbind(name,age)
# Print R object
student_info
# Prints the class of R object
class(student_info)
```

In the above R code, **cbind()** combines two vectors and stores them in the student_info object. Print the R object to see the resultant containing two vectors combined by column.

```
name age
[1,] "Tom" "18"
[2,] "Kim" "20"
[3,] "Sam" "17"
[4,] "Julie" "21"
[1] "matrix"
```

The class of the R object is a matrix.

## Combining Two Vectors in R into Data Frame

Using the **data.frame()** function of a base R package, we can combine two vectors into a data frame.

Let’s practice with an example of concatenating two vectors to a data frame in R.

Let’s create vectors for employees like names and salaries. Use **data.frame()** function to combine two vectors in R.

```
# Create vectors name and salary and use data.frame() to combine them
name = c("Ish","Ted","Mike","Gui")
salary <- c(4500, 3000, 2700,5500)
# Combine vectors in R
emp_info <- data.frame(name,salary)
# Print the data frame
emp_info
# Print the class of the object
class(emp_info)
```

In the above R code, use the **data.frame()** function, it combines two vectors into a data frame and prints the object. The **class()** function gets the class of R object which is the data frame in our case.

```
name salary
1 Ish 4500
2 Ted 3000
3 Mike 2700
4 Gui 5500
[1] "data.frame"
```

## Combining Multiple Vectors to Data Frame in R

Using the **cbind.data.frame()** which is wrapper of data.frame() function, we can combine multiple vectors into a data frame.

Let’s practice with an example to combine multiple vectors to the data frame using cbind.data.frame()

Create multiple vectors and use cbind.data.frame() wrapper method to split matrix columns into data frame arguments and convert character columns to factors.

```
# Create multiple vectors
name = c("Ish","Ted","Mike","Gui")
salary <- c(4500, 3000, 2700,5500)
age <- c(30,32,28,35)
# combine multiple vectors
emp_info <- cbind.data.frame(name,salary,age)
emp_info
class(emp_info)
```

The output of the above R code is:

```
name salary age
1 Ish 4500 30
2 Ted 3000 32
3 Mike 2700 28
4 Gui 5500 35
[1] "data.frame"
```

Using the **cbind()** and **data.frame()** function in R, we can combine two or multiple vectors in R.
