R works with numerous data types. Some of the most basic types to get started are:
4.5 are called numerics.4 are called integers. Integers are also numerics.TRUE or FALSE) are called logical.Note how the quotation marks on the right indicate that "some text" is a character.
Change the value of the:
my_numeric variable to 42.my_character variable to "universe". Note that the quotation marks indicate that "universe" is a character.my_logical variable to FALSE.
Note that R is case sensitive!
# Change my_numeric to be 42
my_numeric <- 42.5
# Change my_character to be "universe"
my_character <- "some text"
# Change my_logical to be FALSE
my_logical <- TRUE
# Change my_numeric to be 42
my_numeric <- 42
# Change my_character to be "universe"
my_character <- "universe"
# Change my_logical to be FALSE
my_logical <- FALSE
test_object("my_numeric", incorrect_msg = "Have you correctly changed the declaration of `my_numeric` so it contains the value 42?")
test_object("my_character", incorrect_msg = "Have you correctly changed `my_character` to `\"universe\"`? Don't forget the quotes!")
test_object("my_logical", incorrect_msg = "Have you correctly changed `my_logical` to `FALSE`? All letters of `FALSE` should be capitalized!")
success_msg("Great work! Continue to the next exercise.")
Replace the values in the editor with the values that are provided in the exercise. For example:
my_numeric <- 42 assigns the value 42 to the variable my_numeric.
