This handout demonstrates using R.

1. Click R icon to start
2. Use the command "Library" to download packages. 
   Example: library(fSeries)

  (You may also click on "Packages" to select a package.)
3. Set your working directory (the directory in which you store 
   the data file) using the command "setwd".
   Example: setwd("C:/teaching/bs41202")

4. Use the command "read.table" to load the data.
   Example: da=read.table("m-ibm2604.txt")

5. You may perform analysis.

6. The followings are basic operations in R
   (a) addition: s=a+b
   (b) subtration: d=a-b
   (c) multipication: p = a*b
   (d) division: d = a/b
   (e) power: c = a^b
   (f) natural log: c = log(a)
   (g) square-root: c = a^0.5 (or c = sqrt(a))

7. Type q() to exit R.
