Append a Single Value to a List

Here we are having an created list with some elements and we are going to append  a single value to list using [[]].

Syntax:

list1[[length(list1)+1]] = value

where,

  • list1 is the input list
  • value is the value to be appended
  • length[list1)+1 is to append a value at the last

Example: R program to append 12 to the list

R




# create a list of integers
list1 = list(c(1, 2, 3, 4, 5))
 
# display
print(list1)
 
print("---------")
 
# add element 12 to the list using length()
list1[[length(list1)+1]] = 12
 
# display
list1


Output:

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

[1] "---------"
[[1]]
[1] 1 2 3 4 5

[[2]]
[1] 12

Time complexity is O(n)

The auxiliary space is O(n)
