What is a List?
You met with lists in the previous section. In simple wording, a list is a data type similar to a vector allowing for storing values of different types.
To create list in R, use the list() function, passing all the values you want to store as the parameters. For example, we can store a single text string, number, and logical value in one 'container'.
# Creating a list
test <- list("Text", 42, TRUE)
# Output list value
test
# Creating a list test <- list("Text", 42, TRUE) # Output list value test
As you can see, the list output is much larger than the vector one.
