1Getting Started withRRis a freely available programming language and environment for statistical computing andgraphics which provides a wide variety of statistical and graphical techniques: linear and non-linear modelling, statistical tests, time series analysis, classification, clustering, etc.You candownload1it and use it from home. We useRin this course because it knows alot about proba-bility (e.g., pdfs and cdfs of many distributions), makes it very easy to use vectors and matrices,and is easier to learn than other computer programming languages you may have heard of likeC++ or Java.The computers in the School of Mathematics, Statistics and Operations Research (MSOR)student computing laboratories use a Unix operating environment.This exercise is meant tohelp you take the first and most difficult steps: successfully getting on the computer, connectingto the Unix system, running R, and subsequently reversing these steps for the first time.Note.The first five steps of this exercise apply to the Unix operating system on the computers inthe MSOR computing labs. If you are doing this exercise on a Windows or Mac-OS environment,then assuming you have R installed, you start R by double-clicking on the left mouse button,as you would with any other application. You can then proceed to step 6 below.Step 1.Enter the statistical computing laboratory CO535 and locate an available workstation.It will normally show a blank screen or the login window.Step 2.Move the mouse to terminate the screensaver and redisplay the login window (thescreen may take a few seconds to become bright again), then type your MSOR username(followed by aReturn) and password (followed by aReturn) at the keyboard.Your MSOR username is in general the same as your VUW SCS login name, but youmust set this up at MSOR once before you can use it at MSOR. Follow the instructions inthe document"Computer Account Registration"which is a coloured A4 notice foundon the door of each MSOR computer laboratory. [To summarise, you use the usernameregisterand the passwordregisterto initiate the activation process, then follow theinstructions on the screen.]Step 3.If the login proceeds successfully, the screen will show a panel of icons at the bottom.
