How to Append Key/Value Pair to List Object in R (Example Code)
In this tutorial you’ll learn how to append a key/value pair to a list object in R.
Creating Example Data
my_list <- list() # Initialize empty list |
my_list <- list() # Initialize empty list
my_key <- "this_is_my_key" # Define key my_key # Display key in RStudio console # [1] "this_is_my_key" |
my_key <- "this_is_my_key" # Define key my_key # Display key in RStudio console # [1] "this_is_my_key"
my_value <- 99999 # Define value my_value # Display value in RStudio console # [1] 99999 |
my_value <- 99999 # Define value my_value # Display value in RStudio console # [1] 99999
Example: Append Key/Value Pair to List Using Square Brackets
my_list[my_key] <- my_value # Adding key/value pair to empty list my_list # Display updated list in RStudio console # $this_is_my_key # [1] 99999 # |
my_list[my_key] <- my_value # Adding key/value pair to empty list my_list # Display updated list in RStudio console # $this_is_my_key # [1] 99999 #
