The attached patch corrects a dead link in the treering documentation. The URL in the manual [1] refers to a personal home page belonging to Christine Hallman (user "hallman") on the website of the University of Arizona Laboratory of Tree-Ring Research (LTRR). It seems that the LTRR personal homepages have been moved to a new root directory [2] and that Hallman's webpage is no longer there.
I have contacted Dr. Hallman. She confirmed that the LTRR hosting has changed and that she has not set up her website on a new host. Also, I have not managed to find any other photographs of the Methuselah Walk. So the page on the Wayback Machine [3] is the best option I see for now. Dr. Hallman also told me that she has more photographs of the tree, and she has offered to publish them in order that we may reference more photographs eventually. I have used approximately the following procedure to build and confirm that the result is formatted properly. (I'm think all of these lines are necessary, but I am not sure that this is the right order.) ./configure --without-recommended-packages cd src/library make all docs Rdfiles cd - make bin/R -e 'help(treering)' I found other dead links in the base documentation, but I thought most should be kept for reference, as they were usually links to a publisher's webpage for a particular journal article or book. The link of present interest just provides context about the tree whose rings were measured, so I think it is okay to change the link.
