Common knowledge tells you not to add apples and oranges. But hey, that is what you just did, no :-)? The my_apples and my_oranges variables both contained a number in the previous exercise. The + operator works with numeric variables in R. If you really tried to add "apples" and "oranges", and assigned a text value to the variable my_oranges (see the editor), you would be trying to assign the addition of a numeric and a character variable to the variable my_fruit. This is not possible.
# Assign a value to the variable my_apples
my_apples <- 5
# Fix the assignment of my_oranges
my_oranges <- "six"
# Create the variable my_fruit and print it out
my_fruit <- my_apples + my_oranges
my_fruit
# Assign a value to the variable my_apples
my_apples <- 5
# Fix the assignment of my_oranges
my_oranges <- 6
# Create the variable my_fruit and print it out
my_fruit <- my_apples + my_oranges
my_fruit
test_error(incorrect_msg = "You can do this by setting the `my_oranges` variable to a numeric value, not a string!")
test_object("my_apples", incorrect_msg = "Make sure that `my_apples` still contains `5`.")
test_object("my_oranges", incorrect_msg = "Make sure that `my_oranges` is equal to `6`.")
test_object("my_fruit", incorrect_msg = "The value of `my_fruit` is not correct. It should be 11, the sum of `my_apples` and `my_oranges`.")
test_output_contains("my_fruit", incorrect_msg = "Don't remove the line that prints out `my_fruit`.")
success_msg("Awesome, keep up the good work! Continue to the next exercise.")
You have to assign the numeric value 6 to the my_oranges variable instead of the character value "six". Note how the quotation marks are used to indicate that "six" is a character.
