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”
