Just download what you need and put the files somewhere where you can
find them.

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"

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.
