Question

you will learn how to manually classify and cluster data based on a specific variable using R programming language. consists of retrieving data, classifying, plot a graph and interpretation of the outcomes.

The dataset that are going to be used in this project is “mtcar” that is available in R studio.

Methodology:

Using the number of cylinders (cyl column) in mtcar dataset(below), classify cars as 4-, 6- or 8-cylinders car. For each class, give a color to the values that belong to that class. Then plot a graph for using “mpg” column as x-axis and “qsec” column as y-axis.

Steps:

Read the file using R programming language.
Read values in column “cyl”.
If x =8, then paint as red, if x =6, then paint as green, If x =4, then paint as blue.
Plot the values of the columns mpg and qsec into an x&y graph.
Plot painted values of “cyl” on the same graph.

Finally, you have to add your interpretations of the results. This is very important!
