A Brief Introduction to R
1.1 A Brief History of R and S-PLUS
The development of computer has great impact on every aspects of our daily life. In
statistics, computer has great impact on the statistical methodology as well. Many
newly developed

Matrix Theory
Matrix is important in Mathematics as well as in Statistics. We have seen that data can
be represented by a matrix with row as observation and column as variable. It is a
necessary tool for multivariate statistical analysis which s
Chapter 6
Database Manipulation
We have demonstrated how to select a subset from a data set according to some
specific criteria in previous chapters. In this chapter, a more formal and systematic
introduction of database manipulation is given. In business
Chapter 5
Programming in R
In previous chapters, we have introduced many useful built-in functions in R. In
addition, we can write our own user defined function. The ability of writing user
defined function is very important for researcher. Actually, R ca

Simulation and Interactive Data Analysis
One of the major applications of computer in Statistics is simulation. Simulation
becomes an inevitable tool in statistics nowadays. It can be used in testing and
assessing our statistical methodologies.
Chapter 3
Statistical Graphics
R can produce professional statistical graphics easily. It has extensive graphical
procedures with many options. Note that some options in Rs graphics are very
complicate and involved. Here we only discuss some simple and co
Chapter 8
VBA Programming in EXCEL
We have learned a lot about R programming. In fact, the basic concepts such as loops,
logical control and user-defined function etc are similar in other programming
languages such as C+, PASCAL, BASIC. With little adopti
Chapter 7
More Graphics and Numerical Methods
We have seen graphs and functions plotted using R. Actually there are many more
statistical graphs such as pie charts, bar charts, dot plots and function plotting in R.
We will discuss how to produce these gra
