This is s test to see if we can

##Step 4. Create vectors for A and B with the levels for each factor
A <- rep(c(15,25,15,25), times=3)
B <- rep(c(1,1,2,2), times=3)
###step 5. Create vector for yield data
yield <- c(28,36,18,31,25,32,19,30,27,32,23,29) ##

You use here "readonly" attribute such that readers can only view and copy. The attribute "name" indicates the text box name. You can write down here anything you like. I have just named it as "Privacy Policy" because I will show privacy policy in text box below:

This post is part III of a series of video tutorials for beginners on how to get the R statistical software running under windows. See also part I (Downloading R) and part II (Installing R).

Remember to use the full screen mode, when playing the video,as this gives you a full screen view of my desktop.

After you have installed the R base program, you can start analyzing your data. However, if you are new to using the traditional command line, the next best option is to try out one of the graphical user interfaces. The video presented here shows how you can install the Rcmdr GUI.

This video shows the 2-step process of getting the Rcmdr GUI working under windows. After starting R, you will be given the option to Install packages from the menu option Packages. Select a mirror and then select the Rcmdr packages from the list of available packages. This is a quick process that takes only a few seconds. Start the Rcmdr by selecting Load package under the menu option Packages. As this is the first time you are using the package, a pop-up window will appear giving a list of extra packages to be installed before you can use it. Select yes to install these packages. This is an automatic process but will take a few minutes for all the required packages to be installed. You may want to skip to the end of this video, to see the final part of installation.

You are now ready to use both the GUI menu options and if you cannot find what you want, you can always type in a function in the the script window (works like the command line - Just don't forget to click on the submit button).

See the next post on Working with Rcmdr for an introduction to basic usage of the GUI and how to work with functions from packages not accessible through the menu options.
