Special thanks must go to Dr R.J.Gibbens for his help in introducing me to SPlus. Several
generations of keen and critical students for the Cambridge University Diploma in Mathematical
Statistics (pre 1998) and for the MPhil in Statistical Science have made helpful suggestions which
have improved these worksheets. Readers are warmly encouraged to tell the author
of any further corrections or suggestions for improvements.

The SPlus worksheets were prepared for the MPhil course. Since I retired in September 2005, I
have gradually edited and updated all my worksheets. (This is an ongoing process)
I started to use R in about 1998, after the SPlus worksheets were first constructed, and so many
of the examples given here were used as the basis for my undergraduate worksheets in R: see for
The R worksheets include many more graphs (with the corresponding R code) than are given in
the SPlus worksheets.
