An example of running R script for Chapter 9, problem 3
I just have gone over running R under Mac OS X. With one minor
modification, this is also applicable to Windows (without RExcel).
Here is a little tutorial (I am assuming you already have R).
Save this data file to your 'Desktop':
Save this script to your 'Desktop':
Optional. Check that your files open, by clicking on them. The
script will open with R, and the datafile with TextEdit (on
Mac) and with Notepad (on Windows).
From the menu bar at the top, choose 'Misc/Change Working
Directory' (Mac users) or 'File/Change Working Directory
(Windows users). Set the working directory to the 'Desktop'.
(Mac users: You can alternatively press Apple key followed by D to do
this step, as the Misc menu shows).
Type this into the R GUI console:
> source("Ch9p3Script.R", echo=T)
Watch the output. It solves WebAssign problem 3 for my randomization.
