NU Arithmetic & Vector Operations Recycle Rule for Adding & Subtracting R Programming

Now that you have R installed on your computer, you will begin to get some experience (hands-on) with the software. For this assignment, you are exposed to just 4 features: Arithmetic Operations; Operations on vectors; the Recycle Rule for adding and subtracting vectors; and Creating a S3 Class Object. A separate screen shot is required for execution of each feature. Open R (either command line or R Studio). Enter code that handles the following (show all code, comment for each code line and the computed results in your screen shots):

Screen shot 1: Arithmetic Operations

• assign a value of 144 to x
• assign a value of 6 to y
• add x and y
• subtract y from x
• multiply x times y
• divide x by y
• find the square root of x

Screen shot 2: Operations on vectors

• create a vector (afc) and assign values 2,6,3
• create a vector (nfc) and assign values 6,4,2
• add afc and nfc

Screen shot 3: Recycle Rule for adding and subtracting vectors

• assign values 2,1,8,3 to vector x
• assign values 9,4 to vector y
• add x to y
• notice the warning message – use the Recycle Rule for adding vectors; then
• add x to y and show results
• subtract 1 from x – apply the Recycle Rule for subtracting vectors; then
• subtract y from x and show results

Screen shot 4: Create an S3 Class Object

• create a list – with components: name = Your name, date = today’s date, and score = score you desire on Assignment 2.
• name the class as “graduate student”

Save the screen shots as a MS Word document (*.docx). Then, click the “Write Submission” link below and directly paste your screen shots into this forum OR add the screen shots as a Microsoft Word document attachment (Mac users, please remember to append the “.docx” extension to the filename.).
