Chp. 2: problems 12 (a and b) and 18. For problem 18, also create a Box Plot.

Chp. 3: problem 22. Only use the dataset (ignore the questions in parts a,b,c) and generate 2 Parallel Coordinates charts for online and in-store customers separately. Also create scatter plot matrix for the three numerical columns. Explain the behavior you see in the charts. Explain the differences between online and in-store customers.

Submit a single Word file that includes your discussions and outputs of R charts. Also submit your R command-line history.

NOTE: For generating a Parallel Coordinates chart, use R command parcoord. For instance, with the estate data frame we used in class, the following line would generate a PC chart using all four columns in the data frame:

parcoord(estate[2:5],var.label=TRUE
