How to Extract Several List Elements in R Programming (Example Code)

This post explains how to subset multiple list elements in R programming.

Example Data

example_list <- list(5,        # Constructing an example list
                     c(8, 4, 1),
                     LETTERS[2:5],
                     77777)
example_list                   # Structure of the list
# [[1]]
# [1] 5
# 
# [[2]]
# [1] 8 4 1
# 
# [[3]]
# [1] "B" "C" "D" "E"
# 
# [[4]]
# [1] 77777

Example: Using Index Positions to Subset List

example_list[c(2, 4)]          # Extracting only some list elements
# [[1]]
# [1] 8 4 1
# 
# [[2]]
# [1] 77777
