Create a list

Just like a grocery list, lists in R can be used to hold together items of different data types. Creating a list is, you guessed it, as simple as using the list() function. You could say that a list is a kind of super data type: you can store practically any piece of information in it! Create a list like so:

words <- c("I <3 R")
numbers <- c(42, 24)

my_list <- list(words, numbers)

my_list

[[1]]
[1] "I <3 R"

[[2]]
[1] 42 24

Below, you will create your first list from some of the data you have already worked with!

ibm <- c(159.82, 160.02, 159.84, 160.35, 164.79)
cor_matrix <- cor(cbind(apple, ibm))
