You can use the **as.list()** function to quickly convert a vector to a list in R.

This function uses the following basic syntax:

**my_list <- as.list(my_vector)
**

The following example shows how to use this function in practice.

**Example: Convert Vector to List in R**

The following code shows how to use the **as.list()** function to convert a vector to a list:

**#create vector
my_vector <- c('A', 'B', 'C', 'D')
#convert vector to list
my_list <- as.list(my_vector)
#view list
my_list
[[1]]
[1] "A"
[[2]]
[1] "B"
[[3]]
[1] "C"
[[4]]
[1] "D"
**

We can use the **class()** function to confirm that the new object indeed has a class of list:

**#view class of list
class(my_list)
[1] "list"
**

**Bonus: Append Vector to List**

You might think that you could use the following syntax to append the elements of a vector to a list in R:

#attempt to create list with 6 elements some_list <- list('A', 'B', as.list(c('C', 'D', 'E', 'F'))) #view list some_list[[1]] [1] "A" [[2]] [1] "B" [[3]] [[3]][[1]] [1] "C" [[3]][[2]] [1] "D" [[3]][[3]] [1] "E" [[3]][[4]] [1] "F"

Rather than a list with six elements, the list has three elements and the third element has four sub-elements.

To append the elements of a vector to a list, we must use the following code:

**#define vector
my_vector <- c('C', 'D', 'E', 'F')
#define first list
list1 <- list('A', 'B')
#convert vector to second list
list2 <- as.list(my_vector)
#create long list by combining first list and second list
list3 <- c(list1, list2)
#view result
list3
[[1]]
[1] "A"
[[2]]
[1] "B"
[[3]]
[1] "C"
[[4]]
[1] "D"
[[5]]
[1] "E"
[[6]]
[1] "F"
**

The result is a list with six elements.
