Thanks David, but I have searched my hard drive using the search
utility in Windows (not just c:\temp - the whole drive) for the file
in question and it is not there. I have also used:
data() to see the names of all dataframes in the datasets package as
well as:
data(package=.packages(all.available=TRUE)) to see all available
data sets
Both methods provide an extensive list, but not "daphnia.txt"

A google search suggested that it was at one time available here, and
testing shows that it still is:
http://www.bio.ic.ac.uk/research/mjcraw/therbook/data/Daphnia.txt
Looking inside the first few pages of the book, it appears this should
have been accessible from the book's associated website. I bought the
book several months ago, but it has remained mostly unused because I
found it quite limited in its depth of presentation of topics in which
I had an interest.
