How to Get Names of List Objects in R (Example Code)
In this tutorial you’ll learn how to get the names of list elements in the R programming language.
Introducing Example Data
example_list <- list(A = LETTERS[1:3], # Constructing example list B = 1:7, C = letters[8:2], D = 555) example_list # Showing list in RStudio console # $A # [1] "A" "B" "C" # # $B # [1] 1 2 3 4 5 6 7 # # $C # [1] "h" "g" "f" "e" "d" "c" "b" # # $D # [1] 555 # |
example_list <- list(A = LETTERS[1:3], # Constructing example list B = 1:7, C = letters[8:2], D = 555) example_list # Showing list in RStudio console # $A # [1] "A" "B" "C" # # $B # [1] 1 2 3 4 5 6 7 # # $C # [1] "h" "g" "f" "e" "d" "c" "b" # # $D # [1] 555 #
Example: Extract Names of All List Elements
names(example_list) # Returning names of list objects # [1] "A" "B" "C" "D" |
names(example_list) # Returning names of list objects # [1] "A" "B" "C" "D"
