Tests not working

[emmakarolina]

Chapter 3:
In "Creating a factor variable" tests cause errors, they need to be modified. Currently there are no tests used in the chapter.

One test_function added but need to track the error message directly from datacamp as no error message has been detected in the script. Datacamp message :

Incorrect Submission
Your code contains an error that you should fix:
Error: factors are not allowed

[gdrouard]

Several things were checked and the problem seems to persist. However, this could be because the quantile() function does not take the crim variable as numeric (while it is apparently numeric). The latest commit is supposed to fix this and remove an unnecessary test_function. Need to be built on Datacamp teach for confirmation.
