Labeling List Elements
List elements can be given labels to make them easier to identify and work with.
Assigning Labels on List Creation
To assign labels during the list creation, use the syntax name = value (without quotes around the name) in the list() function.
Example
12test <- list(text = "Text", number = 42, logical = TRUE) test
Assigning Labels to an Existing List
If the list is already created, you can add labels afterward by assigning a vector of labels to names(list).
Example
123test <- list("Text", 42, TRUE) names(test) <- c('text', 'number', 'logical') test
