Thanks again David. Looking again I now see the last line of the
Acknowledgements which directs the reader to the author's website to get the
datafiles. Of all the places I thought to look I had never considered reading
the Acknowlegements! It seems to be that moving it about one line farther in
the book - into the Getting Started chapter - would have been a better idea!
Oh well, I have highlighted the website for future users of my copy!
Cheers,
-Dave

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.

I have a feeling that this is an embarassingly simple fix, but
I've
been at it for most of the morning and can't get things figured
out.
I'm trying to work through some examples in Crawley's The R
Book.
I have installed packages and libraries as described in the book,
but when I try, for example:
data-read.table(c:\\temp\\daphnia.txt, header=T)
I get:
Error in file(file, rt) : cannot open the connection
In addition: Warning message:
In file(file, rt) :
cannot open file 'c:\temp\daphnia.txt': No such file or directory
There is nothing in my c:\temp folder, so I'm not suprised that it
doesn't work, but I can't for the life of me figure out which
package or library I will need to gain access to this and other
data
files used in this book.
This would appear to be more a problem with you lack of
understanding
regarding the file management utilities of Windows. In Linux or a
Mac
you could use the locate function to track down where the file ended
up, but surely whatever Windows version you have allows such
searching.
