Hi! Coral isn''t working from Xen. If you can please try it, maybe i''m just doing something wrong. However it works from outside Xen with the same setup. Can Xen cause this kind of DNS errors? Try something like: http://www.scs.cs.nyu.edu.nyud.net:8090/coral/ or http://www.google.com.nyud....

Can any one give me an explanation on whats going on in this exercise. And any advice on how i should go about it. I dont need any exact codes just yet. But at least a good idea on how to start will be good Thanks Exercise 2: Gunfight at the OK Corral Description Overview This exercise is to create a small ruby program to determine the winners of gunfights, as seen in old Western movies.

Over the last several day, we''ve been getting pretty regular scans from a non-existant host on our port 7. Any idea what they are looking for/what are some of vulnerabilites with echo? Thanks Coral Cook

...gamma-distributed. An example might be the test proposed in Kallioras et al, 2006, Communications in Statistics--Theory and Methods 35: 527-540. Thanks in advance.

Hello! I'm a PhD student working with coral reef fish diversity in Mexico. I want to do species accumulation curves but I have differential sampling effort for each "sample". Do you know or have developed an R script that consider the differential effort of each sample? PRIMER and other programs use each pack of species as a replic...

Hi there, I have been having trouble running negative binomial regression (glm.nb) using library MASS in R v2.15.0 on Mac OSX. I am running multiple models on the variables influencing the group size of damselfish in coral reefs (count data). For total group size and two of my species, glm.nb is working great to deal with overdispersion in my count data. For two of my species, I am getting a mixture of warning and error messages. These species are different from the others in that they have slightly smaller group...

...ow I want to calculate the group average, but WITHOUT each row's value of x. Is there an easy way to do this? I'm sure I'm missing something obvious here, but for the life of me I can't figure it out. Thanks! -- Casey A.

...#39;s value of x before calculating the group mean assigned to that row. I've already tried the aggregate command. That gives me the group means, but does not allow me to assign them to each row in the data set. THANKS! -- Casey A.

Dear David, you asked this question a while ago on the R mailing list and got no answer. I have the same problem and was wondering if you had found a solution Cheers Loic Loic Thibaut, PhD candidate, ARC Centre of Excellence for Coral Reef Studies, School of Marine Biology, James Cook University, Townsville, Qld, 4811, Australia.
