Introduction

Completing this assignment wil answer the following questions:

   How do I start S-PLUS?

   How can I read data into a table from an ASCII file?
   How can I perform calculations on the data?
   How can I transfer material from S-PLUS to Word?

   How can I enter data into a table?
   How can I create graphics based on the data?
   How can I transfer graphics from S-PLUS to Word?

a. Start S-PLUS.   Turn the computer and monitor on.  Enter your 
   user name and password to log in. In Windows select SPlus2000.

b. In an experiment a subject reads sentences on the monitor of a
   computer.  Every time a subject reads a word, he presses a key.
   That word disappears and the following word appears just to the
   right of where that last word was.  At each following key press,
   the word then showing again disappears, and the next word appears.
   For 24 words the time between key presses is given below in
   milliseconds (Source: Edith Kaan & Laurie Stowe, Developing an
   Experiment, 1995. Techniques and Design, Klapper vakgroep

   446   547   534   495   979   479

   The data are available in in z:\public\share\heeringa\woord.txt.
   Read this ASCII file into S-PLUS. Define the column of the table
   and choose a good variable name.

c. Calculate the average, the median and the standard deviation. 
   These results will appear in the output window.
   
d. Transfer the results of the calculations to Word.
   
e. In the Leiden linen industry there are records of how many bolts of
   cloth were produced annually in the years 1651 - 1670.  The
   production figures below are given in thousands of items.  (Source:

   lakenindustrie. II. De nieuwe tijd. De lakenindustrie en verwante
   industrieen ('s-Gravenhage 1939) 930-931).

   Create a new table and enter this data.

f. Divide the data into five classes: <- 90, 91-105, 106-120, 121-135, 
   136 ->.   Produce a histogram based on this in which each staff of the
   histogram corresponds to one class.
   
g. Transfer the histogram to Word.
   
h. The Word document contains the results of c. and f.  Work on the
   document to create a good report.  Print the result out and
   turn it in (mail box, James Hammerton, 4th floor, central area)
