bookLabeling 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

12
test <- list(text = "Text", number = 42, logical = TRUE) test
copy

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

123
test <- list("Text", 42, TRUE) names(test) <- c('text', 'number', 'logical') test
copy
