How to get Sub List in R


How to get Sub List in R ?

Answer

To get a sublist in R, you can use the indexing operator [] to specify the range of elements.



✐ Examples

1 Get Sublist from a List with Elements

In this example,

  1. We create a list named my_list with some elements.
  2. We use the indexing operator [] to get a sublist from my_list. The operator takes a vector of indices specifying the elements to include in the sublist.
  3. The indexing operation returns a new list containing the specified range of elements.
  4. We print the sublist to standard output.

R Program

my_list <- list(1, 2, 3, 4, 5)
sub_list <- my_list[2:4]
print(paste('Sublist:', toString(sub_list)))

Output

Sublist: 2, 3, 4

2 Get Sublist from Another List with Different Indices

In this example,

  1. We create a list named my_list with some elements.
  2. We use the indexing operator [] to get a sublist from my_list by specifying different start and end indices.
  3. The indexing operation returns a new list containing the specified range of elements.
  4. We print the sublist to standard output.

R Program

my_list <- list(10, 20, 30, 40, 50, 60)
sub_list <- my_list[3:5]
print(paste('Sublist:', toString(sub_list)))

Output

Sublist: 30, 40, 50
