ordisurf (pkg vegan) gives implausible result
I'm having trouble with the ordisurf function in the vegan package. I have created an ordination plot (cmdscale) of 60 samples based on Bray-Curtis dissimilarities, and would like to overlay various soil edaphic characteristics as possible clues to the clustering I observe in my plot. However, I find that ordisurf creates a surface on the plot that is a perfect, even gradient - and

reception of (Vegan) envfit analysis by manuscript reviewers
I'm getting lots of grief from reviewers about figures generated with the envfit function in the Vegan package. Has anyone else struggled to effectively explain this analysis? If so, can you share any helpful tips? The most recent comment I've gotten back: "What this shows is which NMDS axis separates the communities, not the relationship between the edaphic factor and the

R mailing list archive difficulty
Hi, people! This is my first babble on this list, please be kind! :-) Last Tuesday, I wrote to the (likely) Webmaster of the R site to report a little problem, but also to ask for advice about how to get a bulk copy of the mailing list archives, from 2002 to now. While I quite understand that from Tuesday to now, there has been little time, and it is only normal that I did not receive a reply

Idiom for submit button?
What is the rails idiom for submit buttons on forms? All other field types have helpers, but button_to creates its own form, so should not be used. I''ve looked in "Agile Web Dev. with Rails" but can''t see what I should do instead. Is this "difficult" because it runs counter to AJAX type forms? And, related, is there a way to ensure that hitting return in

find()ing rows w/ NULL columns?
Agile Web Development with Rails doesn''t seem to have NULL in the index [or my eyes have failed me again], and web searching turns up lots of SQL statements containing NOT NULL. I have a table of loans, and I want to record when something was loaned and returned. The loan date can''t be null, or there''d be no entry in the table. The return date must be something

RMagick problems
I read the 13th recipe in the book "Rails Recipes" from Chad Fowler. I install with gem the gruff-library (gem install gruff). After the installation, I download the "rmagick-win32-1.13.0_IM-6.2.9-3.zip" file and install it on my win32-machine. It was successfully! So, I create a controller with script/generate. In a method, which I wrote after the creation, I''ll make

Error messages: relative paths seem weakly handled?
I create my rails app, with modifications to the default from a script. Having had to upgrade rails once, and knowing that this is likely to happen again because of the rapid updating of rails, it seems the most sensible way to do it. As a result, I often do /bin/rm -rf csestore and then run my script from another window to repopulate it. So naturally, to save having to cd into csestore, and

I'm running R 2.5.1 on XP. I have just tried a really simple version of the model to see if it would run before I put all the variables in. I have attached all the variables to the
