If you are a total “newbie” in S-plus (or R; a different non-commercial software originated from same S language; learning any one will be enough to work in another), get at least S-plus 4.0 ® or higher or R 1.3.1 § or higher version and just type the commands after “ > ” sign given here in “commands window” in S-plus or in “R console” in R. In most cases I presented the respective results as well, just in case you like to match your results with me. Also whenever I used # [….] after any command, write the command with out # [….]. Just try yourself; when time comes, you will know by yourself. If you don’t exclude them, don’t worry, the command will still execute in its original format! You know what : you don’t need to know anything (but a little Statistics and Linear Algebra) to learn R / S-plus, cause they themselves will guide you to be correct since software today are built in such a user-friendly way. Command writing perfection is not the necessary to workout any job here. I checked all commands provided here in S-plus 4.0. Have fun while poking around the following commands! Good luck!!
