HW 8: Chap 8 Carefully read Section 9.1 for your IE project. Read the R code forChapter 8.
1. 8.4.
2. 8.9. Here are some R hints on how to generate contour plots
• Use the “seq” function in R to generate your x values (type ?seq into the R console
to see what arguments this function takes)
• Generate the y values using the “outer” function. Note that one of the inputs to the
outer function is a function too. You need to write this function yourself.
• Now use the command like contour(x = X1, y = X2, z = Y, nlevels = 10). Be sure
you input your variables using the names you assigned to them.

$8How Our Dissertation Writing Service Works
First, you will need to complete an order form. It's not difficult but, if anything is unclear, you may always chat with us so that we can guide you through it. On the order form, you will need to include some basic information concerning your order: subject, topic, number of pages, etc. We also encourage our clients to upload any relevant information or sources that will help.
Complete the order form
Once we have all the information and instructions that we need, we select the most suitable writer for your assignment. While everything seems to be clear, the writer, who has complete knowledge of the subject, may need clarification from you. It is at that point that you would receive a call or email from us.
Writer’s assignment
As soon as the writer has finished, it will be delivered both to the website and to your email address so that you will not miss it. If your deadline is close at hand, we will place a call to you to make sure that you receive the paper on time.
