[R] can't find daphnia.txt and others while working through Crawley's R-Book
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. -- David.

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 -Dave CC: r-help@r-project.org From: dwinsem...@comcast.net To: dreamwat...@hotmail.com Subject: Re: [R] can't find daphnia.txt and others while working through Crawley's R-Book Date: Thu, 15 Apr 2010 12:28:54 -0400 On Apr 15, 2010, at 11:42 AM, David Hardie wrote: 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.

The files associated with the book can be found on the author's website here: http://www.bio.ic.ac.uk/research/mjcraw/therbook/index.htm http://www.bio.ic.ac.uk/research/mjcraw/therbook/data/ Just download what you need and put the files somewhere where you can find them.

Re: [R] can't find daphnia.txt and others while working through Crawley's R-Book
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!
