Converting list to vector

There is a drawback with the list, i.e., we cannot perform all the arithmetic operations on list elements. To remove this, drawback R provides unlist() function. This function converts the list into vectors. In some cases, it is required to convert a list into a vector so that we can use the elements of the vector for further manipulation.

The unlist() function takes the list as a parameter and change into a vector. Let see an example to understand how to unlist() function is used in R.

Example

# Creating lists.  
list1 <- list(10:20)  
print(list1)  
  
list2 <-list(5:14)  
print(list2)  
  
# Converting the lists to vectors.  
v1 <- unlist(list1)  
v2 <- unlist(list2)  
  
print(v1)  
print(v2)  
  
adding the vectors  
result <- v1+v2  
print(result)

Output:

[[1]]
[1] 1 2 3 4 5

[[1]]
[1] 10 11 12 13 14

[1] 1 2 3 4 5
[1] 10 11 12 13 14
[1] 11 13 15 17 19
