Determine the median value for mpg
Use the median to create a new column in the data set named
mpglevel, which is 1 if mpg>median and otherwise is 0. Make sure
this variable is a factor. We will use mpglevel as the target
(response) variable for the algorithms.
Use the names() function to verify that your new column...

QUESTION 2
If you set up your initial review of the literature using the
Matrix Method, you already have a start on the Matrix Indexing
System. However, the indexing system differs from the Matrix
Method. The Matrix Method is a strategy for acquiring, analyzing,
and writing a synthesis of a review of the scientific literature.
In contrast, the Matrix Indexing System provides a way of coping
with all the information and documents that you use or create as a
result...
